2827. And thou hast not withheld thy son, thine only one, from Me. That this signifies the unition of the Human with the Divine by the utmost of temptation, is evident from the signification of “thy son,” namely, Isaac, as being the Divine rational (explained before), or the Divine Human, for this begins in the rational (n. 2106, 2194); which is called the “only one,” because it was the only-begotten (see n. 2772); and from the signification of “not withholding from me” as being to cause it to be united, namely, to the Divine Itself. That the unition was effected by the utmost of temptation, is manifest from all that precedes.
