Arcana Coelestia # 3052
3052. 'To the city of Nahor' means kindred matters of doctrine. This is clear from the meaning of 'a city' as doctrine, dealt with in 402, 2449, and from the representation of 'Nahor' as that which is kindred; for Nahor was Abram's brother, from whom Bethuel descended, and from him Rebekah. Facts and matters of doctrine are distinct and separate from each other in that matters of doctrine are formed out of facts. Matters of doctrine look to a use and are acquired through reflecting on facts. They are called kindred here because of their derivation from things that are Divine.
Look
'Look not back behind thee,' as in Genesis 19:17, means that Lot, who represents the good of charity, should not look to matters of doctrine. 'To look up,' is to look to celestial things. In Genesis 18:22, looking signifies thinking because seeing denotes understanding.
