“…they made war with Bera king of Sodom, and with Birsha, king of Gomorrah…”  Gen. 14:2

Even though the Sodomites were a proud and wealthy people (see Ezek. 16:49), they knew what it meant to be in subjection. In Genesis, 14, four Assyrian kings made war with the kings of the five cities of the plain, including Sodom and Gomorrah.  They served Chedorlaomer, king of Elam for 12 years.
