3375. And I will set up the oath which I sware unto Abraham thy father. That this signifies confirmation, is evident from the signification of an “oath,” or of “swearing,” as being confirmation (n. 2842). It is not here said to “set up the covenant” made with Abraham, but the “oath,” for the reason that a “covenant” is predicated of the celestial or of good, but an “oath” of the spiritual or of truths (n. 3037), which are the subject here treated of. And for the same reason in what follows it is not said of Isaac that he “made a covenant with Abimelech,” but that he “sware a man to his brother” (verse 31); whereas it is said of Abraham that he and Abimelech “made a covenant” (Genesis 21:32; see Psalms 105:8-10). By the confirmation here referred to which is signified by an “oath,” there is meant the conjunction of the Lord with those who are in His kingdom; for an “oath” is the confirmation of a covenant; and by a “covenant” is signified conjunction (n. 665, 666, 1023, 1038, 1864, 1996, 2003, 2021).

2003. I, behold, My covenant is with thee. That this signifies the union of the Divine Essence with the Human Essence, is evident from the signification of a “covenant,” as being conjunction (see n. 665, 666, 1023, 1038). That here “covenant” signifies the union of the Divine Essence with the Human Essence, is evident from this signification, and also from the internal sense of what precedes, consequently from the very words, “My covenant is with thee.”
