4259. 'And I will make your seed like the sand of the sea which cannot be counted for multitude' means the fruitfulness and multiplication then. This is clear from the meaning of 'seed' as faith that comes from charity, and also charity itself, dealt with in 1025, 1447, 1610, 2848, 3373; and 'making it like the sand of the sea which cannot be counted for multitude' obviously means the multiplication of these. 'Fruitfulness' is used in reference to the good of charity, and 'multiplication' to the truth of faith, 913, 983, 2846, 2847.

983. 'being fruitful' means goods stemming from charity, and 'multiplying' means truths of faith which they were now to receive as increases. This is clear from the meaning of both expressions in the Word where 'being fruitful', or bearing fruit, always has reference to charity, while 'multiplying' has reference to faith. See what has been stated already about the meaning of these two expressions in 43, 55. And by way of further confirmation let the following places from the Word be brought forward: In Jeremiah,

Return, O estranged children; I will give you shepherds after My own heart, and they will feed you with knowledge and intelligence, and it will be that you will be multiplied and you will be fruitful in the land. Jeremiah 3:14-16.

Here 'being multiplied' manifestly stands for the growth of knowledge and intelligence, that is, of faith, while 'being fruitful' stands for goods stemming from charity. Indeed these words describe the establishment of the Church, in which faith or 'multiplying' comes first.

[2] In the same prophet,

I will gather the remnant of My flock out of all the lands where I have driven them, and I will bring them back to their folds, and they will be fruitful and be multiplied. Jeremiah 23:3.

This refers to the Church which has been established, and so is 'to be fruitful' as regards the goods of charity and 'to be multiplied' as regards the truths of faith. In Moses,

Furthermore I will have regard for you and make you fruitful, and multiply you, and I will establish My covenant with you. Leviticus 26:9.

The subject at this point in the internal is the celestial Church, and sense therefore 'being fruitful' has reference to goods of love and charity, 'being multiplied' to goods and truths of faith. In Zechariah,

I will redeem them, and they will be multiplied as they have been multiplied. Zechariah 10:8.

It is evident from the promise that they are to be redeemed that 'being multiplied' here has reference to truths of faith.

[3] In Jeremiah,

The city will be built upon its mound, and out of them will come confession and the voice of those who are playing, and I will multiply them and they will not grow fewer; and its sons will be as they were of old. Jeremiah 30:18-20.

This refers to the affections for truth and to the truths of faith. Affections for truth are expressed by 'confession and the voice of those who are playing', while increases in truths of faith are expressed by 'being multiplied'. Here 'sons' also stands for truths.
