'Adversary' in the Bible

But now the LORD my God hath given me rest on every side, so that there is neither adversary nor evil occurrent.

And the LORD stirred up an adversary unto Solomon, Hadad the Edomite: he was of the king's seed in Edom.

And God stirred him up another adversary, Rezon the son of Eliadah, which fled from his lord Hadadezer king of Zobah:

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