Genesis 14:13-16

14:13 A fugitive came and told Abram the Hebrew. Now Abram was living by the oaks of Mamre the Amorite, the brother of Eshcol and Aner. (All these were allied by treaty with Abram.) 14:14 When Abram heard that his nephew had been taken captive, he mobilized his 318 trained men who had been born in his household, and he pursued the invaders as far as Dan. 14:15 Then, during the night, Abram divided his forces against them and defeated them. He chased them as far as Hobah, which is north of Damascus. 14:16 He retrieved all the stolen property. He also brought back his nephew Lot and his possessions, as well as the women and the rest of the people.
