Genesis 14:1-3

And it came about in the days of Amraphel king of Shinar, Arioch king of Ellasar, Chedorlaomer king of Elam, and Tidal king of Goiim,

that they made war with Bera king of Sodom, and with Birsha king of Gomorrah, Shinab king of Admah, and Shemeber king of Zeboiim, and the king of Bela (that is, Zoar).

All these kings came as allies to the Valley of Siddim (that is, the Salt Sea).
