That this signifies those who are in falsities, is evident from the signification of “sons,” as being truths, and in the opposite sense falsities, or those who are in truths or falsities (n. 489, 491, 533, 1147, 2623, 2803, 2813, 3373, 3704), here those who are in falsities, because by the sons of Jacob, or Joseph’s brethren, are represented those who are in faith separate, thus those who have extinguished Divine truth, and hence are in falsities—as was shown above.
Arcana Coelestia # 1147
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)
