1 Kings 11:21-25

But when Hadad heard in Egypt that David lay down with his fathers and that Joab the commander of the army was dead, Hadad said to Pharaoh, “Let me go, so that I may go to my own country.”

However, Pharaoh said to him, “But what have you lacked with me that you are here, requesting to go to your own country?” And he answered, “Nothing; nevertheless you must let me go.”

God also raised up another adversary against him, Rezon the son of Eliada, who had fled from his master Hadadezer, king of Zobah.

And he gathered men to himself and became leader of a marauding band, after David killed those of Zobah; and they went to Damascus and stayed there, and reigned in Damascus.

So he was an adversary to Israel all the days of Solomon, along with the harm that Hadad inflicted; and he felt disgust for Israel and reigned over Aram.
