2623. A son. That this signifies the Divine rational is evident from the signification of a “son.” In the internal sense of the Word a “son” signifies truth (n. 489, 491, 533); and as truth is the chief thing in the rational (n. 2072, 2189), the rational is also signified by a “son;” but here the Divine rational, in which principally there is good, which Isaac, who is the “son,” also represents (concerning which hereafter).

8056. A land flowing with milk and honey. That this signifies where are gladness and joy, is evident from the signification of “a land flowing with milk and honey,” as being what is pleasant and what is delightful (see n. 5620, 6857), thus gladness and joy. It is said “gladness and joy,” because in the Word “gladness” is predicated of truth, and “joy” of good; in like manner “what is pleasant” and “what is delightful;” moreover “milk” is predicated of the truth of good, and “honey” of the good of truth.
