Genesis 14:13-15

And there came one that had escaped, and told Abram the Hebrew; for he dwelt in the plain of Mamre the Amorite, brother of Eshcol, and brother of Aner: and these {were} confederate with Abram. {plain: Heb. plains} And when Abram heard that his brother was taken captive, he armed his trained {servants}, born in his own house, three hundred and eighteen, and pursued {them} unto Dan. {armed: or, led forth} {trained: or, instructed} And he divided himself against them, he and his servants, by night, and smote them, and pursued them unto Hobah, which {is} on the left hand of Damascus.
