Charles Ellicott Commentary 1 Kings 11:23

"And God raised up [another] adversary unto him, Rezon the son of Eliada, who had fled from his lord Hadadezer king of Zobah." — 1 Kings 11:23 (ASV)

Rezon the son of Eliadah. —The name Rezon, which is not unlike the “Rezin” of 2 Kings 16:0, appears to signify “prince,” and might naturally mark the founder of a new power. In 1 Kings 20:18 we read of a Hezion, king of Damascus, who would belong to this generation, and may be identical with Rezon. The tradition quoted by Josephus (Ant. vii. 5, 2) from Nicolaus of Damascus, that for ten generations from the days of David, all the kings of Syria bore the name of Hadad, probably means only that the title Hadad was the official title of the monarchy.
