Genesis 14:13

Then an escapee came and reported this to Abram the Hebrew. Now Abram was living near the Oaks of Mamre the Amorite, a brother of Eshcol and Aner, all of whom were bound by treaty to Abram.

¶ And there came one that had escaped, and told Abram the Hebrew; for he dwelt in the plain of Mamre the Amorite, brother of Eshcol, and brother of Aner: and these were confederate with Abram.
