Genesis 14:11-15

Then they took all the possessions of Sodom and Gomorrah and all their food supply, and departed.

They also took Lot, Abram’s nephew, and his possessions and departed, for he was living in Sodom.

Then a survivor came and told Abram the Hebrew. Now he was residing by the oaks of Mamre the Amorite, brother of Eshcol and brother of Aner, and they were allies with Abram.

When Abram heard that his relative had been taken captive, he led out his trained men, born in his house, numbering 318, and went in pursuit as far as Dan.

Then he divided his forces against them by night, he and his servants, and defeated them, and pursued them as far as Hobah, which is north of Damascus.
