2194. Behold, Sarah thy wife shall have a son. That this signifies the rational that was to be Divine, is evident from the signification of a “son” and of “Sarah,” and also of “Isaac” who should be born to her. Both “son” and “Sarah,” and also “Isaac,” signify that which is of the Lord’s rational. (That a “son” is truth may be seen above, n. 489, 491, 533, 1147; also that “Sarah” signifies rational truth, n. 2173; and that “Isaac” signifies the Divine rational, n. 1893, 2066, 2083.) The human with every man begins in the inmost of his rational (as before said, n. 2106); and so also the Lord’s Human: that which was above it was Jehovah Himself, differently from any other man whatever. As the human begins in the inmost of the rational, and as the Lord made all the Human that was with Himself Divine, He first made the rational itself so from its inmost, which, when made Divine is represented and signified (as before said) by “Isaac.”

491. The same things are signified by “sons” and “daughters” in this chapter (verses 4, 7, 10, 13, 16, 19, 26, 30), but such as is the church, such are the “sons and daughters” that is, such are the goods and truths; the truths and goods here spoken of are such as were distinctly perceived, because they are predicated of the Most Ancient Church, the principal and parent of all the other and succeeding churches.
