'Adversary' in the Bible

for we are sold, I and my people, to be destroyed, to be slain, and to perish. But if we had been sold for bondmen and bondwomen, I had held my peace, although the adversary could not have compensated for the king's damage.

And Esther said, An adversary and an enemy, even this wicked Haman. Then Haman was afraid before the king and the queen.
