Hadadezer, the the son of Rehob, was the king of Zobah, which in ancient times was the name of an area north of the city of Damascus, Syria. He fought military battles several times against King David. David defeated him at the Euphrates River and captured 1,700 of his horsemen and 20,000 foot soldiers. David also took the golden shields used by Hadadezer's servants and brought them to Jerusalem (2 Samuel 8:3-12).
The name Hadadezer means "Hadad is help."
