8185. 'And let the children of Israel come into the middle of the sea on dry ground' means in order that those belonging to the spiritual Church may pass through in safety and without falsity flowing in. This is clear from the meaning of 'coming into (or entering) the middle' as passing through; from the representation of 'the children of Israel' as those belonging to the spiritual Church, dealt with often; and from the meaning of 'on dry ground' as in safety and without falsity flowing in. Falsities arising from evil are meant by 'the waters' of that sea, 8137, 8138, and therefore 'dry ground' means without falsity. 'Dry' and 'drying up' have a similar meaning in David,

You broke in pieces the heads of Leviathan, You split open fountain and river, You dried up rivers of strength. Psalms 74:14-15.

'Drying up rivers of strength' stands for dispersing quite powerful falsities.

[2] In Zechariah,

I will gather them, for I will redeem them. I will bring them back from the land of Egypt, and gather them from Assyria. And I will bring them to the land of Gilead and Lebanon. He will go through the sea of distress; but he will strike the waves in the sea, and dry up all the depths of the River. And the pride of Asshur will be thrown down, and the rod of Egypt will depart. And I will render them strong in Jehovah. Zechariah 10:8-end.

This refers to those who in spiritual matters trust in themselves and their own wisdom, also to the dispersing of falsities through temptations. 'The land of Egypt' stands for factual knowledge; 'Assyria' stands for reasonings based on that knowledge; 'going through the sea of distress' stands for temptations; 'striking the waves in the sea, and drying up the depths of the River' stands for dispersing falsities from there; and 'the pride of Asshur will be thrown down, and the rod of Egypt will depart' stands for trusting no longer in their own wisdom but in wisdom received from the Lord, which is meant by 'I will render them strong in Jehovah'.

[3] Likewise in Isaiah,

He who says to Jerusalem, You will be dwelt in, and to the cities of Judah, You will be built, and I will raise up her waste places. He who says to the abyss, Be dry! and I will dry up your rivers. Isaiah 44:26-27.

'Saying to the abyss, Be dry!' and 'drying up its rivers' stand for dispersing evils and falsities. But when 'waters' means truths, 'drying up' means a state that is truthless or devoid of truth, as in Isaiah,

I will pour out waters upon the thirsty land, and streams upon the dry. Isaiah 44:3.

'Waters' and 'streams' stand for truths, 'the dry land' for the place that is truthless.

[4] In Jeremiah,

O sword against the Chaldeans and against the inhabitants of Babel! O sword against its horses and against its chariots! A drought on its waters, in order that they may dry up! Jeremiah 50:35, 37-38.

'The Chaldeans' stands for those who render truths profane, and 'the inhabitants of Babel' for those who render forms of good profane, 1182, 1283, 1295, 1304, 1306-1308, 1321, 1322, 1326. 'Sword' stands for truth fighting against falsity, or for falsity fighting against truth, and from this for vastation, 2799, 4499, 6353, 7102; 'horses' stands for the power of understanding, 2761, 2762, 3217, 5321, 6125, 6534; 'chariots' stands for doctrinal teachings, 5321, 8146, 8148; and 'a drought on its waters, in order that they may dry up' stands for truths with no life at all in them owing to falsification.

But when the expressions 'dry' or 'drying up' are used in the Word in connection with other things, such as trees, plants, harvest, or bones, those things take on a contrary meaning. Also, in relation to the sea actual land is called the dry land; and in that case 'the dry land' has reference to good, and 'the sea' to truth.

6125. 'In exchange for horses' means factual knowledge supplied from the understanding. This is clear from the meaning of 'horses' as ideas forming the understanding, dealt with in 2760-2762, 3217, 5321; and since they are spoken of in connection with Egypt, which means factual knowledge, 'horses' here are factual knowledge supplied from the understanding. But what factual knowledge supplied from the understanding is must be stated. There is an understanding part and there is a will part in the human mind, and these are situated not only in his internal man but also in his external. The human understanding is developing and growing from early childhood through to manhood, and it consists in a discernment of things gained from experience and formal knowledge, also a discernment of causes from effects as well as of consequences from a chain of causes. Thus the understanding part consists in a comprehension and perception of such things as are part of everyday life, public and private. An inflowing of light from heaven brings it into existence, and for that reason everyone's understanding is capable of being made more perfect. Understanding is given to everyone in accordance with his effort to make use of what he knows, in accordance with the life he leads, and in accordance with his individual character; no one lacks it provided he is of sound mind. A person is given it to the end that he may have freedom of choice, that is, have the freedom to choose good or evil. Unless he possesses an understanding like the one just described, he has no power of his own to make that choice; thus nothing could possibly be made his own.

[2] In addition to this it should be recognized that the understanding part of a person's mind is that which receives what is spiritual, so that it is the recipient of spiritual truth and good. For no good at all, that is, no charity, nor any truth at all, that is, any faith, can be instilled into anyone if he does not have that understanding part; but they are instilled in the measure that he does have it. This also explains why a person is not regenerated by the Lord until adult life when he does possess an understanding. Till then the good of love and the truth of faith fall like seed into utterly infertile soil. But once a person has been regenerated his understanding serves the function of enabling him to see and perceive what good is and from this what truth is. For the understanding converts things belonging to the superior light of heaven into those belonging to the inferior light of the natural world, as a consequence of which the former are then seen within the latter in the same way as a person's inner affections are seen in his face when it lacks all pretence. And because the understanding serves that function, many places in the Word where the spiritual side of the Church is referred to refer also to its power of understanding, a matter which will in the Lord's Divine mercy be dealt with elsewhere.

[3] From all this one may now see what is meant by factual knowledge supplied from the understanding, namely known facts which lend support to the things a person grasps and perceives with his understanding, whether those things are bad or good. Such facts are what are meant in the Word by 'horses from Egypt', as in Isaiah,

Woe to those who go down into Egypt for help, and rely on horses and trust in chariots because they are many, and on horsemen because they are extremely strong, but do not look to the Holy One of Israel and do not seek Jehovah. For Egypt is man (homo), not God; and his horses are flesh, not spirit. Isaiah 31:1, 3.

'Horses from Egypt' stands for factual knowledge supplied from a perverted understanding.

[4] In Ezekiel,

He rebelled against him by sending his ambassadors to Egypt, that ha might give him horses and many people. Will he prosper? Will he who does this be rescued? Ezekiel 17:15.

'Horses from Egypt' again stands for factual knowledge supplied from a perverted understanding, which knowledge is resorted to in matters of faith, though there is no belief in the Word, that is, in the Lord, apart from what that knowledge provides. Thus no belief ever comes to exist, for within a perverted understanding a negative attitude reigns.

[5] The destruction which such factual knowledge underwent is represented by the drowning of Pharaoh's horses and chariots in the Sea Suph; and since that knowledge is meant by 'horses' and false matters of doctrine by 'chariots', his horses and chariots are mentioned so many times in the description of that event, see Exodus 14:17-18, 27, 26, 28. And the Song of Moses and Miriam consequently contains these words,

Pharaoh's horse went, also his chariot, also his horsemen, into the sea; but Jehovah made the waters of the sea come back over them. Sing to Jehovah, for He has highly exalted Himself; He has thrown the horse and its rider into the sea. Exodus 15:19, 21.

[6] Similar factual knowledge is also meant by the things required before-hand for a king over Israel, in Moses,

If they desire a king, from among their brothers shall a king be set over them. Only let him not multiply horses for himself nor lead the people back into Egypt in order to multiply horses. Deuteronomy 17:15-16.

'A king' represented the Lord as regards Divine Truth, 1672, 1728, 2015, 2069, 3009, 3670, 4575, 4581, 4789, 4966, 5044, 5068, thus as regards intelligence since this comes, when it is genuine, from Divine Truth. The need for intelligence to be acquired through the Word, which is Divine Truth, and not through factual knowledge taken from one's own understanding is meant by the injunction that the king should not multiply horses or lead the people back into Egypt in order to multiply horses.
