'Adversary' in the Bible

and he was there in the wilderness forty days, being tempted by the Adversary, and he was with the beasts, and the messengers were ministering to him.

And, having called them near, in similes he said to them, 'How is the Adversary able to cast out the Adversary?

and if the Adversary did rise against himself, and hath been divided, he cannot be made to stand, but hath an end.

and these are they by the way where the word is sown: and whenever they may hear, immediately cometh the Adversary, and he taketh away the word that hath been sown in their hearts.

and he, having turned, and having looked on his disciples, rebuked Peter, saying, 'Get behind me, Adversary, because thou dost not mind the things of God, but the things of men.'
