2772. He said, Take I pray thy son. That this signifies the Divine rational begotten by Him, is evident from the signification of a “son,” as being the rational (see n. 2623); here the Divine rational, because by the son is meant Isaac; and that he represents the Lord’s Divine rational has been shown above (n. 1893, 2066, 2083, 2630). And as the Lord made His rational Divine by His own power, as has been often said, by “thy son” is also signified that it was begotten by Him (see n. 1893, 2093, 2625).

2033. Thou shalt keep My covenant. That this signifies still closer union, is evident from the signification of a “covenant,” as being union and conjunction (treated of before, at verses 2, 4, and 7; also in Part First, n. 665, 666, 1023, 1038). The repeated mention here of “covenant,” so frequently mentioned before, denotes a closer union. In the historical sense, which relates to Abraham, nothing else can be said than that he is to keep the covenant; but in the internal sense, in which the Lord is treated of, what is historical vanishes, and the things that can be predicated of Him succeed in its place, which relate to a closer union. The unition of the Lord’s Human Essence with His Divine Essence was not effected all at once, but through the whole course of His life, from infancy to the last of His life in the world. Thus He ascended continuously to glorification, that is, to union; according to what is said in John:

Jesus said, Father glorify Thy name; there came a voice from heaven: I have both glorified and will glorify it again (John 12:28).
