'Enemy' in the Bible

But of late my people is risen up as an enemy: ye strip off the mantle with the garment from them that pass by securely, that are averse from war.

Rejoice not against me, O mine enemy: though I fall, I shall arise; when I sit in darkness, Jehovah shall be a light unto me.

And mine enemy shall see it, and shame shall cover her which said unto me, Where is Jehovah thy God? Mine eyes shall behold her; now shall she be trodden down, as the mire of the streets.
