'Enemy' in the Bible

When I saw their fear, I stood and said to the nobles and officials and the rest of the people: “Do not be afraid of them; [confidently] remember the Lord who is great and awesome, and [with courage from Him] fight for your brothers, your sons, your daughters, your wives, and for your homes.”

Therefore you gave them into the hand of their enemy, and they brought trouble to them. Then in the time of their trouble they cried out to you, and you heard from the heavens, and according to your great compassions, you gave them saviors, and you saved them from the hand of their enemies.
