Arcana Coelestia #3947
3947. 'And will you take also my son's dudaim?' means that in that case the conjugial element linking natural good to external truth would be taken away. This is clear from the meaning of 'taking' here as taking away; from the meaning of 'dudaim' as the conjugial element, dealt with in 3942; and from the meaning of 'son' as truth, dealt with in 489, 491, 533, 1147, in this case external truth since it is Leah who is speaking and who, as shown above, means external truth.
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.
