'Enemy' in the Bible

Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy.

But while men slept, his enemy came and sowed tares among the wheat, and went his way.

He said unto them, An enemy hath done this. The servants said unto him, Wilt thou then that we go and gather them up?

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

Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you.

And said, O full of all subtilty and all mischief, thou child of the devil, thou enemy of all righteousness, wilt thou not cease to pervert the right ways of the Lord?

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

The last enemy that shall be destroyed is death.

Am I therefore become your enemy, because I tell you the truth?

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

Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God.
