'Adversary' in the Bible

But now that the Lord my God has given me rest [from war] on every side, there is neither adversary nor misfortune [confronting me].

Then the Lord stirred up an adversary against Solomon, Hadad the Edomite; he was of royal descent in Edom.

God also stirred up another adversary for Solomon, Rezon the son of Eliada, who had fled from his master, Hadadezer king of Zobah.

So Rezon was an adversary to Israel all the days of Solomon, along with the evil that Hadad inflicted. Rezon hated Israel and reigned over Aram (Syria).
