Rezon in the Bible Encyclopedia - ISBE
            re'-zon (rezon; Rhazon): Son of Eliadah, and a subject of 
Hadadezer, king of Zobah (1 Ki 11:23). The name appears to be 
given as chezyon; Hazein (1 Ki 15:18; see HEZION), where he is 
the father of Tabrimmon, whose son Ben-hadad I is known 
through his leaaue with Asa, king of Judah. When David 
conquered Zobah, Rezon renounced his allegiance to Hadadezer 
and became powerful as an independent chief, capturing 
Damascus and setting up as king. Along with Hadad, the noted 
Edomite patriot, he became a thorn in the side of Solomon, the 
one making himself obnoxious in the South, the other in the 
North, of the kingdom of Israel, both being animated with a 
bitter hatred of the common foe. It is said of Rezon that he 
"reigned over Syria" (1 Ki 11:25), and if the surmise adopted 
by many scholars is correct that he is the same as Hezion (1 
Ki 15:18), then he was really the founder of the dynasty of 
Syrian kings so well known in the history of this period of 
Israel; and the line would run: Rezon, Tabrimmon, Ben-hadad I, 
and Ben-hadad II.
