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.

8991. 'And he shall serve him forever' means into eternity. This is clear from the meaning of 'serving' as obeying, for slaves are those who obey and masters those who give orders (the fact that those represented by 'slaves' are those who did what was good from obedience, not from charitable affection, is clear from things stated previously); and from the meaning of 'forever' as into eternity. In the sense of the letter 'forever' here means servitude with his master to the end of his life; but in the internal or spiritual sense it means into eternity, because it refers to the state after death. The expression 'into eternity' is used because those who do what is good from faithful obedience and not from charitable affection, who were represented by 'slaves', cannot ever be brought in the next life to a state of good, that is, so that their actions spring from good; for everyone's life remains with them after death. What a person is like when he dies, so he continues to be, in keeping with the common saying, Where the tree falls, there it lies. Not that he continues to be what he is like around the time of death but what the whole course of his life has made him like when he dies. Therefore those who have learned during life in the world to do what is good solely from obedience, not from charity, remain the same into eternity. They are perfected in obedience, it is true, but they do not attain any degree of charity.
