Arcana Coelestia #4207
4207. 'The God of their father' means from the Supreme Divine. This is clear from the meaning of 'the God of one's father' as the Supreme Divine. For in the internal sense when the expression 'father' is used in the Word good is meant, see 3703; and when 'the Lord's Father' is mentioned there, that is, when the Lord uses the name 'Father', the Divine Good dwelling within Him is meant, 3704. Divine Good is the Supreme Divine, whereas Divine Truth is that which proceeds from Divine Good and which is also called the Son. Furthermore 'father' in this instance is used to mean Terah who was the father of them both - of Abraham and Nahor - and 'Terah' represents the common stock from which Churches sprang, see 3778. In the relative sense therefore 'Abraham' represents the genuine Church and 'Nahor' the Church consisting of gentiles, as stated immediately above in 4206.
Deuteronomy 21:11-13
11
and see among the captives a beautiful woman, and you have a desire to her, and would take her to you as wife;
12
then you shall bring her home to your house; and she shall shave her head, and pare her nails;
13
and she shall put the clothing of her captivity from off her, and shall remain in your house, and bewail her father and her mother a full month: and after that you shall go in to her, and be her husband, and she shall be your wife.
