Hadadezer in Wikipedia

("Hadad is my help"); also known as Adad-Idri (Assyr.) and possibly the same as Bar-Hadad II (Aram.); Ben-Hadad II (Heb.), was the king of Aram Damascus at the time of the battle of Qarqar against the Assyrian king Shalmaneser III in 853 BCE. He and Irhuleni of Hamath led a coalition of eleven kings (listed as twelve) at Qarqar (including Ahab of Israel). He fought Shalmaneser six other times, twice more with the aid of Irhuleni and possibly the rest of the coalition that fought at Qarqar. He is mentioned in the inscriptions on the Tel Dan Stele; he seems most likely to be the unknown author's father. He was succeeded by Hazael after he was suffocated in the night by him. Some accounts claim that Hazael was in fact his son.
