4589. 'For this also is a son for you' means spiritual truth. This is clear from the meaning of 'a son' as truth, dealt with in 489, 491, 533, 1147, 2623, 3373, in this case spiritual truth since Benjamin is the son referred to here, who represents the spiritual of the celestial.

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.
