Genesis 14:12-14 New English Translation (NET Bible)
12 They also took Abram’s nephew Lot and his possessions when they left, for Lot was living in Sodom.
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 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.
