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).

10636. 'Because this is a marvel which I am doing with you' means the essential nature of the Word in every single part. This is clear from the representation of 'Moses' as the Word, dealt with in the places referred to in 9372, so that 'a marvel which Jehovah was about to do with him' means that it will be Divine in every single part, as above in 10633.
