Genesis 14:13-16

Then one who escaped came and told Abram the Hebrew. And he was living at the oaks of Mamre the Amorite, brother of Eshcol and brother of Aner. They were allies with Abram. When Abram heard that his relative was taken captive, he summoned his trained men, born in his house, three hundred and eighteen of them, and he went in pursuit up to Dan. And he divided his trained men against them at night, he and his servants. And he defeated them and pursued them to Hobah, which is north of Damascus. And he brought back all the possessions. And he also brought back Lot, his relative, and his possessions, and the women and the people as well.
