3737. And Jehovah shall be to me for God. That this signifies that the Divine natural also was Jehovah, is evident from the series of things in the supreme internal sense, which treats of the unition of the Lord’s Human with His Divine; but in order that this sense may appear, the thought must be abstracted from the history of Jacob and be kept fixed on the Lord’s Divine Human, and in this case on His Divine natural, which is represented by Jacob. The human itself, as before repeatedly stated, consists of the rational, which is the same as the internal man, and of the natural, which is the same as the external man, and also of the body, which serves the natural as a means or outermost organ for living in the world, and through the natural serves the rational, and moreover through the rational, serves the Divine. Inasmuch as the Lord came into the world in order that He might make the whole human in Himself Divine, and this according to Divine order; and as by Jacob is represented the Lord’s natural, and by his life of sojourning, in the supreme sense, how the Lord made His natural Divine, therefore here, where it is said, “if I shall return in peace to the house of my father, Jehovah shall be to me for God,” there is signified the unition of the Lord’s Human with His Divine, and that as to the Divine natural also He should be Jehovah, through the unition of the Divine Essence with the Human, and of the Human with the Divine. This unition is not to be understood as being a unition of two who are distinct from each other, and conjoined merely by love; as a father with a son, when the father loves the son and the son the father; or as when a brother loves a brother, or a friend a friend; but it is a real unition into a one in order that they may be not two but one (as the Lord also repeatedly teaches); and because they are a one, therefore the whole Human of the Lord is the Divine being or Jehovah (see n. 1343, 1736, 2156, 2329, 2447, 2921, 3023, 3035).

913. That they may spread themselves over the earth. That this signifies the operation of the internal man on the external, and that “being fruitful” signifies increasings of good, “multiplying” increasings of truth, and “upon the earth” in the external man, is evident from the connection of the things, and also from what has been before said and shown about the signification of “being fruitful” which in the Word is predicated of goods, and about that of “multiplying” which is predicated of truths. That “earth” signifies the external man has likewise been shown before; so that we need not dwell longer on these significations in order to confirm them. Here the subject is the operation of the internal man on the external after the man has been regenerated, showing that good is for the first time made fruitful, and truth multiplied, when the external man has been reduced to correspondence or obedience. This can never be so before, because what is corporeal opposes what is good, and what is sensuous opposes what is true, the one extinguishing the love of good, and the other extinguishing the love of truth. The fructification of good and the multiplication of truth take place in the external man; the fructification of good in his affections, and the multiplication of truth in his memory. The external man is here called “the earth” over which they spread themselves, and upon which they become fruitful and multiply.
