5 kings who fought four in the days of Abraham and Lot, Genesis 14

Genesis 14:2-4 ... these kings went to war against

Bera king of Sodom,
Birsha king of Gomorrah,
Shinab king of Admah,
Shemeber king of Zeboyim,
and the king of Bela (that is, Zoar).

All these latter kings joined forces in the Valley of Siddim (that is, the Dead Sea Valley). For twelve years they had been subject to Kedorlaomer, but in the thirteenth year they rebelled.
(Also see verse 8)
