REZON (rē'zŏn, Heb. rezôn, nobleman). A citizen of Zobah, a small country NW of Damascus. Evidently a rebel, he took advantage of an invasion of Zobah by David and led a band of guerrillas to Damascus where he made himself king. Hadadezer, the rightful king, was overthrown by David, and Rezon met little opposition (1Kgs.11.23-1Kgs.11.25). He must have been a wise ruler, for Syria soon became a strong nation. He made an alliance with Hadad of Edom and began to harass Israel whom he hated (1Kgs.11.25). He is almost certainly the same as Hezion mentioned in 1Kgs.15.18, though Hezion could have been his son. In either case, he founded a dynasty of strong Syrian rulers, among them the noted Ben-Hadad I and his son Ben-Hadad II.
