God raised up another opponent for Solomon: Rezon, Eliada's son, who had escaped from Zobah's King Hadadezer.
References for 1 Kings 11:23
Rezon recruited men and became leader of a band when David was killing them. They went to Damascus, stayed there, and ruled it.
Throughout Solomon's lifetime, Rezon was Israel's opponent and added to the problems caused by Hadad. Rezon hated Israel while he ruled as king of Aram.
