Arcana Coelestia #3680
3680. 'And had sent him away to Paddan Aram' means the beginning of the manifestation [of the Natural] through cognitions of that good. This is clear from the meaning of 'he sent him away' as the beginning of its manifestation, dealt with above in 3674 and from the meaning of 'Paddan Aram' as the cognitions of truth, dealt with in 3664. They are called cognitions of good because all truths are cognitions of good. Truths which are not rooted in good, or which do not have good as the end in view, are not truths. But insofar as they look to doctrine they are called cognitions of truth.

3664. 'Go to Paddan Aram' means the cognitions of such truth. This is clear from the meaning of 'Aram' or Syria as cognitions, dealt with in 1232, 1234, 3249. The reason 'Paddan Aram' means cognitions of truth is that it was situated in Syria of the [Two] Rivers, where Nahor, Bethuel, and Laban lived; for 'Syria' means the cognitions of truth, see 3051. Paddan Aram has also been referred to previously in 25:20, and is mentioned again in 31:18 below; and in those places too it means cognitions of truth.
