Arcana Coelestia #10651
10651. 'And you take their daughters for your sons' means affections for evil linked to truths. This is clear from the meaning of 'taking', when it refers to marriage, as being linked to; from the meaning of 'daughters' as affections for good, and in the contrary sense as affections for evil, dealt with in 2362, 3963; and from the meaning of 'sons' as truths, dealt with in 489, 491, 533, 1147, 3373, 4257, 9807, 10490.
Arcana Coelestia #1147
1147. 'And sons were born to them' means matters of doctrine deriving from those three. This is clear from the meaning of 'sons' in the internal sense as truths of faith, and also as falsities. Consequently matters of doctrine, both true and false, are meant, for such are the doctrines of Churches. That 'sons' has such a meaning, see above in 264, 489, 491, 533.
