Arcana Coelestia #9344
9344. 'You shall not make a covenant with them and their gods' means no contact with evils and falsities. This is clear from the meaning of 'making a covenant' as being joined together, dealt with in 665, 666, 1023, 1038, 1864, 1996, 2003, 2021, 6804, 8767, 8778, thus also being in contact with, for people who communicate with one another are joined to one another; from the meaning of the inhabitants of the land, to whom 'those with whom they were not to make a covenant' refers here, as evils, dealt with just above in 9342; and from the meaning of 'their gods' as falsities, dealt with in 4402 (end), 4544, 7873, 8867, 8941.
Arcana Coelestia #1996
1996. 'I will make My covenant between Me and you' means the union of the Internal Man, which was Jehovah, with the Interior Man. This is clear from the meaning of 'a covenant' as a joining together, for as often as a covenant between Jehovah and man is mentioned in the Word, nothing else is meant in the internal sense by a covenant than the Lord's being joined to man. The covenants made so many times between Jehovah and the descendants of Jacob had no other representation. As this point has been confirmed in Volume One, in 665, 666, 1023, 1038, 1864, it would be superfluous to do so again here. The Lord's Internal Man was Jehovah because He was conceived from Him, while the Interior Man is represented here by Abram. Consequently 'the covenant between Me and you' means the union of the Internal Man, or Jehovah, with the Interior Man, and so with the Lord's Human Essence.
