'Adversary' in the Bible

But now Jehovah my God has given me rest on every side: there is neither adversary nor evil event.

And Jehovah stirred up an adversary to Solomon, Hadad the Edomite; he was of the king's seed in Edom.

God stirred him up yet an adversary, Rezon the son of Eliada, who had fled from Hadadezer king of Zobah, his lord.

And he was an adversary to Israel all the days of Solomon, besides the mischief that Hadad did; and he abhorred Israel, and reigned over Syria.
