'Enemy' in the Bible

Ye have heard that it was said, Thou shalt love thy neighbor, and hate thine enemy:

but while men slept, his enemy came and sowed tares also among the wheat, and went away.

And he said unto them, An enemy hath done this. And the servants say unto him, Wilt thou then that we go and gather them up?

and the enemy that sowed them is the devil: and the harvest is the end of the world; and the reapers are angels.

Behold, I have given you authority to tread upon serpents and scorpions, and over all the power of the enemy: and nothing shall in any wise hurt you.

and said, O full of all guile and all villany, thou son of the devil, thou enemy of all righteousness, wilt thou not cease to pervert the right ways of the Lord?

But if thine enemy hunger, feed him; if he thirst, give him to drink: for in so doing thou shalt heap coals of fire upon his head.

The last enemy that shall be abolished is death.

So then am I become your enemy, by telling you the truth?

And yet count him not as an enemy, but admonish him as a brother.

Ye adulteresses, know ye not that the friendship of the world is enmity with God? Whosoever therefore would be a friend of the world maketh himself an enemy of God.
