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).

5515. 'The sons of our father' means having the same origin. This is clear from the meaning of 'the sons' as truths, dealt with in 489, 491, 533, 1147, 2623, 3373, and from the meaning of 'father' as good, dealt with in 2803, 3703, 3704. Consequently 'the sons of our father' means truths springing from good, thus truths having the same origin; they are all truths originating in one and the same good.
