Arcana Coelestia #3051
3051. 'And went to Aram Naharaim' means resulting cognitions of truth. This is clear from the meaning of 'Aram' or Syria as cognitions of good, dealt with in 1232, 1234. 'Aram Naharaim' - or Syria of the [Two] Rivers - means cognitions of truth. This is because 'Naharaim', or 'rivers', means intelligence which consists of cognitions of truth, as may be seen from the places quoted from the Word in 108, 109, 2702, and from many others, which will in the Lord's Divine mercy be presented elsewhere.
