Genesis 14:13-16

13And there came one that had escaped, and told Abram the Hebrew: now he dwelt by the oaks of Mamre, the Amorite, brother of Eshcol, and brother of Aner; and these were confederate with Abram. 14And when Abram heard that his brother was taken captive, he led forth his trained men, born in his house, three hundred and eighteen, and pursued as far as Dan. 15And he divided himself against them by night, he and his servants, and smote them, and pursued them unto Hobah, which is on the left hand of Damascus. 16And he brought back all the goods, and also brought back his brother Lot, and his goods, and the women also, and the people.
