Arcana Coelestia #9808
9808. 'From the midst of the children of Israel' means in heaven and in the Church. This is clear from the meaning of 'Israel' as those who belong to the Church, thus in the abstract sense the Church itself, dealt with in 4286, 6426, 6637, 6862, 6868, 7035, 7062, 7198, 7201, 7215, 7223, 8805, 9340. And since 'Israel' means the Church it also means heaven; for heaven and the Church make one, and also the Church is the Lord's heaven on earth. Every member of the Church furthermore has heaven within himself when truth and at the same time good which come from the Lord reside in him.
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.
