Genesis 14:12-13

12They also carried off Abram’s nephew Lot and his possessions, since he was living in Sodom. 13A man who had escaped came and reported this to Abram the Hebrew. Now Abram was living near the great trees of Mamre the Amorite, a brother Or a relative; or an ally of Eshkol and Aner, all of whom were allied with Abram.
