Turn, O backsliding sons; I will give you shepherds according to Mine heart, and they shall feed you with knowledge and intelligence and it shall be that ye shall be multiplied and made fruitful in the earth (Jer. 3:14-16), where "to be multiplied" manifestly denotes growth in knowledge and intelligence, that is, in faith, and "to be made fruitful" denotes the goods of charity; for it there treats of the implantation of the church, in which faith or "multiplication" comes first. Again:

I will gather the remnant of My flock out of all lands whither I have driven them, and will bring them again to their folds, and they shall be fruitful and multiplied (Jer. 23:3), speaking of a church already planted, consequently to be "made fruitful" as to the goods of charity and to be "multiplied" as to the truths of faith. So in Moses:

Moreover I will look to you, and make you to be fruitful, and I will make you to be multiplied, and establish My covenant with you (Lev. 26:9), speaking in the internal sense of the celestial church, wherefore "to be fruitful" is predicated of the goods of love and charity, and "to be multiplied" of the goods and truths of faith. In Zechariah:

I will redeem them, and they shall be multiplied as they have been multiplied (Zech. 10:8);

that "to be multiplied" is here predicated of the truths of faith, is evident from their being to "be redeemed." In Jeremiah:

The city shall be builded upon her own heap, and out of them shall proceed confession, and the voice of them that make merry, and I will cause them to be multiplied, and they shall not be diminished; their sons also shall be as aforetime (Jer. 30:18-20),speaking of the affections of truth, and of the truths of faith; the former being denoted by "confession, and the voice of them that make merry" and the latter by "being multiplied;" "sons" also here denote truths.
