'Enemy' in the Bible

"If your people Israel are defeated by an enemy because they sinned against you, then if they come back to you, renew their allegiance to you, and pray for your help before you in this temple,

"The time will come when the land suffers from a famine, a plague, blight, and disease, or a locust invasion, or when their enemy lays siege to the cities of the land, or when some other type of plague or epidemic occurs.

Even if you go and fight bravely in battle, God will defeat you before the enemy. God is capable of helping or defeating."
