Chedorlaomer was a king of Elam. Located east of Babylon in the time of Abraham (Gen. chap. 14). Chedorlaomer joined up with three other kings, Tidal king of Goiim, Amraphel king of Shinar, and Arioch king of Ellasar.
These four kings conquered five other kings in the land east of the Jordan River, who were subject to them for twelve years. In the thirteenth year the five kings rebelled, but were defeated.
It was in this war, Lot, Abraham's nephew was captured and taken away. Abraham (called Abram at the time) mustered up an army of 318 men, pursued Chedorlaomer as far as Dan, defeated Chedorlaomer and the other kings, and rescued Lot and all the captives.
It was after this battle Abraham met up with Melchizedek, king of Salem, who blessed him.
