Genesis 14:10-14

And the vale of Siddim was full of slimepits; and the kings of Sodom and Gomorrah fled, and fell there; and they that remained fled to the mountain.

And they took all the goods of Sodom and Gomorrah, and all their victuals, and went their way.

And they took Lot, Abram’s brother’s son, who dwelt in Sodom, and his goods, and departed.

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.

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.
