2973. 'Which was in all its borders round about' means exterior cognitions. This is clear from the meaning of 'borders' and of 'round about' as things that are exterior, dealt with in 2936. Thus here '[every] tree which was in the borders round about' means exterior cognitions. Exterior cognitions have to do with the religious observances and matters of doctrine which constitute the external things of the Church, whereas interior cognitions have to do with matters of doctrine which constitute the internal things of the Church. What the external things of the Church are, and what the internal, has been stated several times already.

[2] Furthermore in various places in the Word mention is made of the middle or the midst and of the regions encircling it, as when the land of Canaan is referred to, 'the middle' is used to describe where Zion and Jerusalem are, while the areas encircling describe where the nations are who are round about. 'The land of Canaan' represented the Lord's kingdom, 'Zion' the celestial part of it and 'Jerusalem' the spiritual, and there Jehovah or the Lord had His dwelling-place. The things that were round about, even to the borders, represented celestial and spiritual things spread out and derived in order from there. Where the furthest boundaries lay, there the representatives of celestial and spiritual things ended. Those representatives had their origin in the things that existed in the Lord's kingdom in heaven, where the Lord as the Sun is in the middle, from where all celestial flame and spiritual light radiate. Those nearest to Him dwell in the brightest light, while those who are more remote dwell in less light, and those who are the most remote in the least bright. At this point lie the borders where hell, which is outside heaven, begins.

[3] With celestial flame and spiritual light the position is that the existence of celestial things which are forms of innocence and love, and spiritual things which are forms of charity and faith, is proportional to the heat and light that is received, for those things are the source of all heat and light in heaven. This then is why 'the middle' means that which is inmost, and the encircling regions that which is outermost; and the spacing of the things that radiate in order from the inmost to the outermost is determined by their degree of innocence, love and charity. It is similar with each individual community of heaven. Those members in the middle are the best of its kind, and the love and charity of that kind becomes correspondingly less as these become more remote, that is, as such love and charity exist with members away from the middle.

[4] It is also similar with man. The inmost part of him is where the Lord resides with him, and from there governs the outlying parts. When a person permits the Lord to bring order to the outlying parts so that these correspond to the inmost parts, his state is such that he can be received into heaven, and the inmost, the interior, and the external parts of him act as one. But if the person does not permit the Lord to bring order to those outlying parts so that they correspond, he moves away from heaven, as far away as he is from permitting the Lord to bring that order to them. The fact that man's soul resides in the middle or inmost part of his being and the body in the outlying region or outermost parts is well known, for the body is that which surrounds and clothes his soul or spirit.

[5] With those in whom celestial and spiritual love reigns, good from the Lord flows in by way of the soul into the body, as a consequence of which the body becomes full of light, but with those in whom bodily and worldly love reigns, good from the Lord cannot flow in by way of the soul into the body. Instead their interiors are engulfed in darkness, as a consequence of which the body too becomes full of darkness, according to the Lord's own teaching in Matthew,

The lamp of the body is the eye. If the eye is sound, the whole body is full of light. If the eye is evil, the whole body is full of darkness. If therefore the light is darkness, how great is the darkness! Matthew 6:22-23.

'The eye' means the understanding part, which belongs in the soul, 2701.

[6] But matters are worse still with people whose interiors are 'darkness' while their exteriors seem to be 'full of light'. They are such as outwardly pretend to be angels of light but inwardly they are devils. They are referred to as 'Babel'. These people, when the things that are round about are destroyed, are carried headfirst into hell. This was represented by the city of Jericho whose walls fell down, and the city was given to destruction, after the priests had gone round it seven times with the ark, and had sounded their trumpets, Joshua 6:1-17. The same is meant in Jeremiah,

Set yourselves against Babel round about, all you who bend the bow. Raise a shout over her round about, she has given her hand, her foundations have fallen, her walls have been destroyed. Jeremiah 50:14-15.

From this it is now evident what 'round about' means. Reference is also made several times in the Word to 'the encircling regions', as in Jeremiah 21:14; 46:14; 49:5; Ezekiel 36:3-4, 7; 37:21; Amos 3:11; and elsewhere. By 'the encircling regions' is meant the things that are exterior, concerning which, in the Lord's Divine mercy, more will be said elsewhere.

921. 'Noah built an altar to Jehovah' means a representative of the Lord. This is clear from what has been stated just above. All the religious observances of the Ancient Church were representative of the Lord, as also were those of the Jewish Church. But the chief representative in later times was the altar, and also the burnt offering, which, because it was made from clean beasts and clean birds, represented the same as that of which it was the meaningful sign. Clean beasts represented goods that stem from charity, and clean birds the truths of faith. And when offering these, members of the Ancient Church meant that they were offering gifts of those goods or truths to the Lord. Nothing else can be offered up to the Lord that will please Him. But their descendants, like the gentiles, and also the Jews, corrupted these offerings, for they did not even know that these had such a meaning. They confined worship solely to things of an external nature.

[2] That the altar was the chief representative of the Lord becomes clear also from the consideration that there were altars even among gentiles before all the other religious observances were established, before the Ark [of the Covenant] was made, and before the Temple was built. This is clear from Abram's going on to the mountain east of Bethel, erecting an altar, and calling on the name of Jehovah, Genesis 12:8; from his being commanded to offer Isaac as a burnt offering on an altar, Genesis 22:2, 9, from Jacob's building an altar in Luz, which was Bethel, Genesis 35:6-7; and from Moses' building an altar at the foot of Mount Sinai and offering sacrifice, Exodus 24:4-6. Each of these events took place before the establishment of the sacrificial system and before the construction of the Ark, the place where worship was at a later time celebrated in the wilderness. The fact that gentiles too had altars is clear from what is said about Balaam telling Balak to build seven altars and to prepare seven young bulls and seven rams, Numbers 23:1-7, 15-18, 29-30, and also from the command to destroy the altars of the nations, as in Deuteronomy 7:5; Judges 2:2. Consequently Divine worship involving the use of altars and sacrifices was not something new when it was established among the Jews. Indeed men were building altars, especially those for commemorative purposes, before they ever knew of immolating young bulls and other animals on them.

[3] That 'altars' means a representative of the Lord, and 'burnt offerings' consequent worship of Him, is quite clear from the Prophets and also in Moses where Levi to whom the priesthood was entrusted is the subject,

They will teach Jacob Your judgements and Israel Your law. They will put incense in Your nostrils, and whole (burnt offering) upon Your altar. Deuteronomy 33:10.

This stands for the whole of worship. 'Teaching Jacob His judgements, and Israel His law' stands for internal worship, while 'putting incense in His nostrils, and whole [burnt offering] on the altar' stands for corresponding external worship, and so for the whole of worship. In Isaiah,

On that day a man will look to his Maker and his eyes will regard the Holy One of Israel. And he will not look to the altars, the work of his hands. Isaiah 17:7-8.

Here 'looking to the altars' clearly means representative worship in general, which was to be abolished. In the same prophet,

On that day there will be an altar to Jehovah in the midst of the land of Egypt, and a pillar at its border to Jehovah. Isaiah 19:19.

Here too 'altar' stands for external worship.

[4] In Jeremiah,

The Lord has abandoned His altar, He has abhorred His sanctuary. Lamentations 2:7.

'Altar' stands for representative worship which had become idolatrous. In Hosea,

Ephraim has multiplied altars for sinning, they have been to him altars for sinning. Hosea 8:11.

'Altars' here stands for all representative worship separated from internal, and so stands for what is idolatrous. In the same prophet,

The high places of Aven, the sin of Israel, will be destroyed. Thorn and thistle will grow up on their altars. Hosea 10:8.

Here too 'altars' stands for idolatrous worship. In Amos,

On the day I visit Israel for his transgressions, I will visit the altars of Bethel, and the horns of the altar will be cut off. Amos 3:14.

Here also 'altars' stands for representative worship that had become idolatrous.

[5] In David,

They will bring me to Your holy mountain, and to Your dwellings! Then I will go in to the altar of God, to God my exceeding joy. Psalms 43:3-4.

Here 'altar' clearly stands for the Lord. So the making of an altar in the Ancient and the Jewish Churches stood for a representative of the Lord. Because worship of the Lord was carried out principally by means of burnt offerings and sacrifices, and these principally meant representative worship, it is clear that the altar itself means representative worship itself.
