Genesis 14:10-14

Now the Valley of Siddim was full of tar pits; and the kings of Sodom and Gomorrah fled, and they fell into them. But those who survived fled to the hill country.

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.
