'Enemy' in the Bible

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

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

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