Genesis 14:3-10

And all these joined forces in the Valley of Siddim (that is, the Salt Sea). Twelve years they had served Chedorlaomer, but in the thirteenth year they rebelled. In the fourteenth year Chedorlaomer and the kings who were with him came and defeated the Rephaim in Ashteroth-karnaim, the Zuzim in Ham, the Emim in Shaveh-kiriathaim, and the Horites in their hill country of Seir as far as El-paran on the border of the wilderness. Then they turned back and came to En-mishpat (that is, Kadesh) and defeated all the country of the Amalekites, and also the Amorites who were dwelling in Hazazon-tamar. Then the king of Sodom, the king of Gomorrah, the king of Admah, the king of Zeboiim, and the king of Bela (that is, Zoar) went out, and they joined battle in the Valley of Siddim with Chedorlaomer king of Elam, Tidal king of Goiim, Amraphel king of Shinar, and Arioch king of Ellasar, four kings against five. Now the Valley of Siddim was full of bitumen pits, and as the kings of Sodom and Gomorrah fled, some fell into them, and the rest fled to the hill country.
