Hadadezer bar Rehob
Hadadezer ("Hadad helps") the son of Rehob (Heb. Hadadezer ben Rehob; Aram. Hadadezer bar Rehob) was king of the Aramaean kingdom of Zobah during the early tenth century BC. According to II Samuel, Hadadezer allied with the Ammonites against King David of Israel, but was defeated.[1] Hadadezer's kingdom may previous to this have dominated the Aramaean states.
After Hadadezer of Zobah's defeat, Damascus began its rise to prominence and states like Hamath sent grateful missives to David. Rezon the Syrian, an enemy of King Solomon mentioned in 1 Kings, is recorded as having deserted Hadadezer king of Zobah. After Hadadezer's death, Rezon became king in Damascus and, like Hadad the Edomite, harried Israel's borders.[2]
