3266. And these are the names of the sons of Ishmael. That this signifies the qualities of their doctrinal things, namely, of those who are spiritual, is evident from the signification of “name,” as being quality (see n. 144, 145, 1754, 1896, 2009, 2724, 3006); from the signification of “sons,” as being truths, and also doctrinal things (see n. 489, 491, 533, 1147, 2623); and from the representation of Ishmael, as being those who are spiritual (n. 3263).

1147. And unto them were sons born. That these signify the doctrinals thence derived, is evident from the signification of “sons” in the internal sense, as being the truths of faith, and also the falsities, consequently doctrinal matters; by which both true and false are meant, for such are the doctrinals of churches. (That “sons” have such a signification may be seen above, n. 264, 489, 491, 535)
