208. Behold I have set before thee an open door, and no one is able to shut it. That this signifies that they will be admitted into heaven, and that it will be denied to no one who is of such a quality is evident from the signification of setting before them an open door, as being to admit into heaven, of which we shall treat in what follows; and from the signification of no one is able to shut it, as being that entrance will not be denied; for when a door is shut, entrance is denied, and when it is not shut it is not denied. The reason why it is open to those who are in charity is, that these are treated of in what is written to this church (see above, n. 203). Hence it is evident that by I have set before thee an open door, and no one is able to shut it is signified, that all such will be admitted into heaven, and that it will be denied to none of them. That to set before them an open door signifies to admit them into heaven is evident indeed from common speech, but nevertheless it is from correspondence; for a house and all things belonging to a house correspond to the interiors of man's mind, and from that correspondence they also signify such things in the Word. That this is the case is evident from representatives and appearances in heaven, where there are palaces, houses, rooms, bed-chambers, vestibules, courts, and within them various things for use. These things the angels have from correspondence; whence it is that the wiser angels have palaces more magnificent than those enjoyed by those who are less wise. (But concerning these things, see the work, Heaven and Hell 183-190, where the habitations of the angels of heaven are treated of.) And because palaces, houses, and all the things belonging to a house correspond, it is also evident that outer doors, inner doors, and gates correspond also, and that they correspond to entrance and admission; also when a door is seen open, it is a sign that there is permission to enter, and when it is shut, that there is not.

[2] Moreover, when novitiate spirits are introduced into a heavenly society, a way is opened to them by the Lord which leads to it; and when they come thither a gate is seen with a door at the side, where there are keepers who admit them, and afterwards there are others who receive and introduce them.

From these considerations, it is evident that outer doors (januae), and inner doors (ostia), and gates in the Word signify introduction into heaven; and because the church is the Lord's heaven on earth, they also signify introduction into the church; and because heaven or the church is in man, therefore they also signify approach and entrance with man, concerning which something shall be said presently. And because all the things that signify heaven and the church also signify the things pertaining to heaven and the church, and here introductory things which are truths from good, these being from the Lord; and because those things are from the Lord, and hence are His, indeed are Himself in them, therefore by outer door (janua), inner door (ostium), and gate to heaven and the church, in the highest sense, is meant the Lord. Hence it is evident what the words of the Lord signify in John:

Jesus said: "Verily I say unto you, he that entereth not by the door (janua) into the sheepfold, but climbeth up some other way, the same is a thief and a robber. But he that entereth in by the door is the shepherd of the sheep; to him the porter openeth. I am the door (ostium) of the sheep, by me if any man enter in, he shall be saved, and shall go in and out and find pasture" (10:1, 2, 3, 7, 9).

That to enter in by the door (ostium) here denotes to enter in by the Lord, is evident, for it is said, "I am the door of the sheep." To enter in by the Lord is to approach Him, to acknowledge Him, to believe in Him, and to love Him, as He Himself teaches in many passages. Thus is a man admitted into heaven, and in no other way; therefore the Lord says, "By me if any man enter in, he shall be saved"; and also "he who climbeth up some other way, the same is a thief and a robber."

[3] He therefore who approaches the Lord, acknowledges Him and believes in Him, is said to open the door (ostium) to the Lord, that He may enter in; as in the Apocalypse:

"Behold I stand at the door (ostium) and knock; if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me" (3:20).

How these things are to be understood, will be explained in the following pages, where the things mentioned are treated of. Here we shall only say something concerning the doors (ostia) or gates in man, because it is said, I stand at the door and knock.

There are two ways which lead to man's Rational, one from heaven and the other from the world; by the way from heaven good is introduced, by the way from the world truth is introduced. In proportion as the way from heaven is opened to a man, in the same proportion he is affected with truth, and becomes rational, that is, in the same proportion he sees truth by the light of truth; but if the way from heaven is shut, he does not become rational, because he does not see truth, and yet truth from the light of truth constitutes the Rational. A man may indeed reason concerning truth, and from reasoning or from memory he may speak of it; but he is not able to see whether it is truth or not. To think well concerning the Lord and the neighbour, opens the way from heaven; but to think otherwise shuts that way. Because there are two ways which lead into man, there are also two doors (januae) or gates by which influx enters: by the door or gate which is open from heaven, the spiritual affection of truth from the Lord enters, because good enters by that door, as said above, and all spiritual affection of truth is from good; but by the door or gate which is open from the world, enter all knowledge from the Word, and from preaching thence, because thereby truth enters, as also said above, for knowledges from the Word and from preaching thence are truths. The spiritual affection of truth adjoined to those knowledges constitutes man's Rational, and enlightens it according to the quality of the truth conjoined with good, and according to the quality of the conjunction.

[4] These few observations may be sufficient for the present concerning the gates or doors pertaining to man. Because outer doors (januae), inner doors (ostia), and gates signify admission into heaven and into the church, therefore they also signify truths from good which are from the Lord, because by means of them this admission is effected, as is evident from the following passages. Thus in Isaiah:

"Open ye the gates that the just nation that keepeth faithfulnesses may enter in" (26:2).

According to the sense of the letter it is here meant that those who are just and faithful should be admitted into those cities, but according to the internal sense, that such should be admitted into the church: for gates signify admission; a just nation signifies those who are in good; keeping faithfulnesses signifies those who are thence in truths.

[5] Again:

"Thy gates shall be open continually; they shall not be shut day nor night; to bring unto thee the hosts of the nations, and their kings shall be brought down. And the nation and kingdom that will not serve thee shall perish. Thou shalt call thy walls Salvation, and thy gates Praise" (60:11, 12, 18).

The subject here treated of is the Lord and the church which He was about to establish; and by the above particulars is described the perpetual admission into it of those who are in good and thence in truths. By the gates being open continually, and not shut day nor night, is signified perpetual admission; by the host of the nations are signified those who are in good, and by kings those who are in truths; and that all should serve the Lord is meant by the nation and kingdom that will not serve thee shall perish. (That nation or nations signify those who are in good, may be seen above, n. 175, and that kings signify those who are in truths, n. 31.)

[6] Again:

"Thus said Jehovah to his anointed, to Cyrus, whose right hand I have holden, to subdue nations before him; that I may loose the loins of kings, to open before him the doors (januae) that the gates may not be shut; I will give him the treasures of darkness, and hidden riches of secret places" (45:1, 3).

Here also the Lord is treated of, and the church to be established by Him. By opening the doors (januae), and by the gates not being shut, is signified perpetual admission; by nations and kings are signified those who are in goods and truths, and, in the abstract, goods and truths, as said above; by treasures of darkness and hidden riches of secret places, is signified interior intelligence and wisdom from heaven; for the things that enter by the gate which is open from heaven, and of which we have spoken above, come in secretly, and influence all the things that are with man, whence arises the spiritual affection of truth, whereby things before unknown are revealed.

[7] In Jeremiah:

"If ye bring in no burden through the gates of this city on the Sabbath day, but hallow the Sabbath day, then shall there enter through the gates of this city kings and princes sitting upon the throne of David, riding upon the chariot and on horses, and the city shall be inhabited to eternity" (17:24, 25).

Any one may see what is meant by these things in the sense of the letter; nevertheless it can be known that something more holy is contained in them, because they form part of the Word; and everything in the Word contains those things that pertain to heaven and the church, and these alone are holy; thus what is holy in this passage can only be known from the internal sense. By the Sabbath day in that sense is meant the conjunction of the Divine Human of the Lord with heaven and the church; by the city mentioned in this passage is meant Jerusalem, that is, the church: by bringing in no burden through the gates of the city is meant that they should not admit that which is from man's proprium, but that which is from the Lord. By kings and princes entering into the gates of the city are meant Divine truths, which should then be revealed to them; by their sitting upon the throne of David is meant that these truths are from the Lord. By riding upon the chariot and on horses is meant that thence they would be in the doctrine of truth and in intelligence; and by dwelling there to eternity is meant life and eternal salvation. (That by Sabbath, is signified the conjunction of the Divine Human of the Lord with heaven and the church, may be seen,Arcana Coelestia 8494, 8495, 8510, 10356, 10360, 10367, 10370, 10374, 10668, 10730. That by Jerusalem is signified the church, 402, 3654, 9166. That by burden or work on the Sabbath day is signified not to be led by the Lord but by the proprium, n. 7893, 8495, 10360, 10362, 10365. That by kings and princes are signified those who are in Divine truths, and, in the abstract, Divine truths, see above, n. 29, 31. That by chariot is signified the doctrine of truth, and by horses the Intellectual, see the small work, The White Horse 1-5.)

[8] Again, in the Apocalypse, it is said of the New Jerusalem,

"Having a wall great and high, twelve gates, and at the gates twelve angels, and names written thereon which are the names of the twelve tribes of the sons of Israel; the twelve gates were twelve pearls; the gates of it shall not be shut" (21:12, 21, 25).

That gates signify Divine truths introductory to the New Church, thus those who are in truths from good from the Lord is evident from the explanation of these words in the small work, The New Jerusalem 1, etc.); which is also evident from this consideration, that it is said there were twelve gates, twelve angels upon the gates, and the names of the twelve tribes written thereon, and that the twelve gates were twelve pearls. By twelve are signified all, and is said of truths from good, see Arcana Coelestia 577, 2089, 2129, 2130, 3272, 3858, 3913, similarly by angels, see above, n. 130, 200; also by the twelve tribes of Israel, Arcana Coelestia 3858, 3926, 4060, 6335; and also by pearls.)

[9] In Jeremiah:

"Out of the north evil shall be opened that they may come, and every one set his throne at the door (ostium) of the gates of Jerusalem, and at all its walls round about, because they have forsaken me" (1:14, 15, 16).

The subject here treated of is the destruction of the church: the north signifies falsity, in this case the falsity from which evil is derived; to come and set every one his throne at the door of the gates of Jerusalem, is to destroy the introductory truths of the church by falsities; and at all the walls round about, denotes all the truths that are for a defence.

[10] In Isaiah:

"Howl, O gate; cry, O city; thou, whole Philistia, art dissolved because, from the north cometh smoke" (14:31).

Again:

"The choicest of thy valleys shall be filled with the chariot; and the horsemen shall set themselves in array even to the gate, he hath made bare the covering of Judah" (22:7, 8).

In these passages also the destruction of the Church is treated of; and by the gates there mentioned introductory truths are signified, which are destroyed; those truths are called the covering of Judah, because by Judah is signified celestial love, as may be seen above (n. 119), and those truths cover and protect that love. Again

"The remnant in the city is wasteness, and the gate is smitten even to devastation" (24:12).

[11] In Jeremiah:

"Judah mourned, and the gates thereof languished" (14:2).

In the book of Judges:

"The villages ceased in Israel: he hath chosen new gods; then to assault the gates" (5:7, 8).

In Ezekiel:

"Tyrus hath said over Jerusalem, Aha, she is broken, the doors (januae) of the peoples, she is brought over to me" (26:2).

Here also the subject treated of is the destruction of the church. By Tyrus are signified the knowledges (cognitiones) of truth and good, which are introductory truths; and by Jerusalem is signified the church as to the doctrine of truth. It is therefore evident why Jerusalem is here called the doors (januae) of the peoples; also what is signified by Tyrus saying, "Aha, she is broken, the doors of the peoples; she is brought over to me, I shall be filled."

[12] Since, as said above, by doors (januae) and by gates is signified admission, and, specifically, introductory truths are signified, which are truths from good from the Lord, it is evident what is signified by these in the following places. In David

"Lift up your heads, O ye gates; and be ye lift up, ye doors (ostia) of the world, that the king of glory may come in" (Psalms 24:7, 9).

Again:

Recount the praises of Jehovah "in the gates of the daughter of Zion" (Psalms 9:14).

Again:

"Jehovah loveth the gates of Zion more than all the dwellings of Jacob" (Psalms 87:2).

By Zion and by the daughter of Zion is meant the celestial church. Again, in Isaiah:

"Thy Redeemer, the Holy One of Israel; the God of the whole earth he is called. I will make thy windows of agates, and thy gates of carbuncles" (54:5, 12).

In Matthew:

The five prudent virgins entered into the marriage, "and the door (ostium) was shut," and the five foolish virgins came and knocked, but the door was not opened to them (25:10, 11, 12).

In Luke:

Jesus said "Strive to enter in at the strait gate (portam) for many will seek to enter in, and will not be able. When once the master of the house is risen up, and hath shut to the door (januam), then shall ye begin to stand without, and to knock at the door (januam), saying, Lord, Lord, open unto us; but he shall answer and say unto you, I know you not whence ye are" (13:24, 25).

In these two passages the state of man after death is treated of, that those who are in faith alone, and not in love, cannot be admitted into heaven, even although they should then desire it, and this in consequence of the nature of their faith. And this is what is signified by the door being shut, and their being refused admission when they knocked.

[13] Because gates signify introductory truths, therefore it was ordained among the statutes,

That the elders should sit at the gates and judge (Deuteronomy 21:19; 22:15-21; Amos. 5:12, 15; Zech. 8:16).

It was also therefore commanded, that "They should write the precepts upon the posts and gates" (Deuteronomy 6:8, 9).

And it was also among the statutes,

That the ear of the servant who was not willing to go out free in the seventh year, should be bored through at the door (januam) (Exodus 21:6; Deuteronomy 15:17).

By servants of the sons of Israel were signified those who were in truths and not in good; and by freemen, those who were in good and thence in truths. By the ear being bored through at the door was signified perpetual obedience and servitude, because they were not desirous to be introduced into good by means of truths; for those who are in truth and not in good, are perpetually in a servile state, not being in the spiritual affection of truth; for it is the affection of love that makes man free (as may be seen in The Doctrine of the New Jerusalem 141-149). Moreover introductory truths as to their quality are described by the covering of the door of the tent, and by the covering of the door of the tabernacle (Exodus 26:14, 36, 37; 38:18); also by the numerical measurements of the doors and gates of the house of God and of the temple in Ezekiel (40:6, 8-11, 13-15, 18, 19, 20, 24, 27, 28, 32, 35, 37; 41:1-3, 11, 17-20, 23-25; 42:2, 12, 15; 43:1-4; 44:1-3, 17; 46:1-3, 8, 12, 19; 47:1, 2; 48:31-34). He who knows what the particular numbers there mentioned signify, may know many arcana concerning those truths. Mention is also made of the gates of the house of Jehovah towards the north and towards the east, in the same prophet (8:3, 5; 10:19).

4286. 'And he said, Your name will no longer be called Jacob, but Israel' means the Divine celestial-spiritual at this point, for 'Israel' is the celestial-spiritual man within the natural, and so is the natural man, whereas the celestial[- spiritual] man proper - that is, the rational man - is 'Joseph'. This becomes clear from what is said below about Jacob and Israel, and also about Joseph, for one must begin here by stating what the celestial-spiritual is. At the present day within the Church the existence of the spiritual man and the natural man, or the internal man and the external, is indeed well known; but as to what the spiritual or internal man may be, this is not as yet so well known. Still less is it known what the celestial man is and the fact that this is distinct and separate from the spiritual man. And as this is not known it is impossible to know what the celestial-spiritual man is, meant here by 'Israel', and therefore a brief statement about it must be made.

[2] It is well known that there are three heavens - the inmost heaven, the middle heaven, and the ultimate heaven, or what amounts to the same, the third, second, and first heavens. The inmost or third heaven is celestial, the angels there being called celestial because they are governed by love to the Lord and as a consequence are the ones most closely linked to the Lord. And that being so they excel all other angels in wisdom. They are innocent and are for that reason called embodiments of innocence and wisdom. These angels are divided into internal and external, the internal being more celestial than the external. The middle or second heaven is spiritual, the angels there being called spiritual because they are governed by charity towards the neighbour, that is, by mutual love, the nature of which is such that one angel loves another more than himself. And because their nature is such, intelligence is present within them and for that reason they are called embodiments of intelligence. These angels too are divided into internal and external, the internal being more spiritual than the external. But the ultimate or first heaven is also celestial and spiritual, though not in the same degree as the previous ones; for the natural is closely associated with them, and so for that reason they are called celestial-natural and spiritual-natural. They too are governed by mutual love, but they do not love others more than themselves, only as themselves. What governs them is an affection for good and a knowledge of truth. They also are divided into internal and external.

[3] But what the celestial-spiritual is must also be stated briefly. The term celestial-spiritual applies to those who have been called spiritual immediately above and who are in the middle or second heaven. They are given the name celestial because of their mutual love, and spiritual because of their intelligence arising out of this. The internal members of that heaven are represented by Joseph, and also in the Word are actually called 'Joseph', whereas its external members are represented by Israel, and also in the Word are actually called 'Israel'. The former, namely the internal members who are called Joseph, partake of the rational, whereas the external members who are called Israel partake of the natural, for they are half-way between the rational and the natural. These are the reasons why it has been said that 'Israel' is the celestial-spiritual man within the natural man, and so is the natural man, and that 'Joseph' is the celestial-spiritual man proper, which is the rational man. For in the universal sense all good which flows from love and charity is called celestial, and all truth which derives from this and constitutes faith and intelligence is referred to as spiritual.

[4] These things have been stated so that people may know what is meant by 'Israel'. But by 'Israel' the Lord's Divine celestial-spiritual is meant in the highest sense, whereas the Lord's spiritual kingdom in heaven and on earth is meant in the internal sense. The Lord's spiritual kingdom on earth is the Church, which is called the spiritual Church. And as 'Israel' means the Lord's spiritual kingdom, 'Israel' also means the spiritual man, for the Lord's kingdom exists within all who are spiritual, since each is heaven and also the Church in the smallest form these can take, 4279. As for Jacob, in the highest sense he represents the Lord's natural, both His celestial-natural and His spiritual-natural, and in the internal sense the Lord's kingdom as it exists in the ultimate or first heaven, and so also the corresponding area of the Church. Good within the natural is that which is called celestial here, and truth within it that which is called spiritual. From all this one may see what 'Israel' and 'Jacob' mean in the Word, and also why Jacob received the name Israel.

[5] But these ideas that have been stated will inevitably seem obscure, the chief reason being that few people know what the spiritual man is, and scarcely any what the celestial man is, or consequently that there is any difference between the spiritual man and the celestial man. The reason why they do not know is that no clear difference is perceived between good which is the good of love and charity, and truth which is the truth of faith. And the reason why these are not perceived is that genuine charity does not exist any longer. When something is non-existent no perception of it is possible. And a further reason why they are not perceived is that people do not bother very much about the things that have to do with the life after death, and so about those to do with heaven, but much about things to do with life in the body, and so with things which belong to the world. If people did bother about the things that have to do with the life after death, and so about those which have to do with heaven, they would easily grasp all that has been mentioned above, for that which a person loves he absorbs and grasps with ease, but that which he does not love with difficulty.

[6] The fact that 'Jacob' has one meaning and 'Israel' another is quite evident from the Word, for in its historical sections, and in the prophetical ones too, Jacob is used at one point, Israel at another; and sometimes the two names occur in the same verse. From this it becomes clear that there is an internal sense to the Word, and that without that sense this matter could in no way be known. The use of Jacob at one point, Israel at another is clear from the following,

Jacob dwelt in the land of his father's sojournings. These are the generations of Jacob. Joseph was a son of seventeen years. And Israel loved Joseph more than all his sons. Genesis 37:1-3.

Here Jacob is first called 'Jacob' and immediately after that 'Israel' - Israel being used when Joseph is referred to. Elsewhere,

Jacob saw that there was grain in Egypt; Jacob said to his sons . . . And the sons of Israel came to buy in the midst of others who came. Genesis 42:1, 5.

And after this,

They went up out of Egypt and came to the land of Canaan, to Jacob their father. When they told him all Joseph's words which he had spoken to them the spirit of Jacob their father revived. And Israel said, Enough; Joseph my son is still alive. Genesis 45:25, 27-28.

Then,

And Israel set out and all that he had. God spoke to Israel in visions in the night and said, Jacob, Jacob. And he said, Behold, here I am. And Jacob rose up from Beersheba; and the sons of Israel carried away ¹ Jacob their father. Genesis 46:1-2, 5.

And in the same chapter,

These are the names of the sons of Israel who came into Egypt, Jacob and his sons. Genesis 46:8.

Further on,

Joseph brought in Jacob his father and placed him before Pharaoh. Pharaoh said to Jacob . . . and Jacob said to Pharaoh . . . Genesis 47:7-10.

And in the same chapter,

And Israel dwelt in the land of Goshen. And Jacob lived in the land of Egypt seventeen years. And Israel's days drew near when he must die; he called his son Joseph. Genesis 47:27-29.

Yet again,

And someone reported to Jacob and said, Behold, your son Joseph has come to you, and Israel found some strength in himself and sat up on his bed. And Jacob said to Joseph, God Shaddai appeared to me in Luz. Genesis 48:2-3.

The name Israel is again used in the same chapter in verses 8, 10, 11, 13, 14, 20-21. And finally,

Jacob called his sons and said, Gather together, and hear, O sons of Jacob; and hearken to Israel your father. And when Jacob had finished commanding his sons . . . Genesis 49:1-2, 33.

From all these places it becomes clear that Jacob is called Jacob at one point, Israel at another, thus that Jacob has one meaning, Israel another, that is, one thing is meant when he is called Jacob, another when he is called Israel. They also make it quite clear that this arcanum can in no way be known except from the internal sense.

[7] What 'Jacob' means however, and what 'Israel', has been stated above. In general 'Jacob' in the Word means the external aspect of the Church and 'Israel' the internal, for every Church has an external aspect and it has an internal one, that is, it is internal and also external. And because that which constitutes the Church is meant by 'Jacob' and by 'Israel' and because the Church in its entirety originates in the Lord, both Jacob and Israel therefore mean the Lord in the highest sense - 'Jacob' the Lord's Divine natural, 'Israel' His Divine spiritual. Consequently the external aspect of the Lord's kingdom and of His Church is meant by 'Jacob' and the internal by 'Israel', as becomes additionally clear from the following places in which again each name is used in its own sense. In the prophecy uttered by Jacob, who by then was Israel,

By the hands of the Mighty One of Jacob; from there is the Shepherd, the Stone of Israel. Genesis 49:24.

In Isaiah,

Hear, O Jacob My servant, and Israel whom I have chosen. Fear not, O My servant Jacob, and Jeshurun whom I have chosen. I will pour out My spirit upon your seed, and My blessing upon your sons. This one will say, I am Jehovah's, and another will call himself by the name of Jacob: and he will write with his hand, Jehovah's, and surname himself by the name of Israel. Isaiah 44:1-3, 5.

Here 'Jacob' and 'Israel' plainly stand for the Lord, while Jacob or Israel's 'seed' and 'sons' stand for those whose faith is in Him. In Balaam's prophecy in Moses,

Who will count the dust of Jacob, and its number together with a fourth part of Israel? Numbers 23:10.

And again,

There is no divination against Jacob, nor enchantments against Israel. At that time it will be said to Jacob and to Israel, What has God done? Numbers 23:23.

Further still,

How fine are your tabernacles, O Jacob; your dwelling-places, O Israel. Numbers 24:5.

And again,

A star will arise out of Jacob, and a sceptre out of Israel. Numbers 24:17.

In Isaiah,

My glory will I not give to another. Hearken to me, O Jacob, and O Israel whom I called: I am the same; I am the first; I am also the last. Isaiah 48:11-12.

In the same prophet,

Those who are to come Jacob will cause to take root. Israel will blossom and flower, and the face of the earth will be filled with produce. Isaiah 27:6.

In Jeremiah,

Do not fear, O My servant Jacob, and do not be dismayed, O Israel, for behold, I have saved you from afar. Jeremiah 30:9-10.

In Micah,

I will surely gather Jacob, all of you, I will surely assemble the remnant of Israel, I will put them together, like the sheep of Bozrah. Micah 2:12.

[8] The reason why Jacob received the name Israel is clear from the actual words used when he was given it, which are these,

Your name will no longer be called Jacob, but Israel, for as a prince you have contended with God and with men, and have prevailed.

Israel in the original language means 'one contending as a prince with God', and these words mean in the internal sense that he overcame in the conflicts that accompany temptations; for it was through temptations and the conflicts which take place in temptations ² that the Lord made His Human Divine, 1737, 1813, and elsewhere. And it is temptations and victories in temptations that make the spiritual man. This is why Jacob first received the name Israel after his wrestling - 'wrestling' meaning to undergo temptation, see 4274. It is well known that the Church, or the member of the Christian Church, calls itself Israel, but no one in the Church is an Israel except the one who has become a spiritual man through temptations. The name itself also implies the same. A subsequent confirmation of the fact that Jacob was to be called Israel was also given to him, as is clear from the following words further on,

And God appeared again to Jacob when coming from Paddan Aram, and blessed him; and God said to him, Your name is Jacob; your name will no longer be called Jacob, but Israel will be your name. And He called his name Israel. Genesis 35:9-10.

The reason for this confirmation will be discussed below.
