'Enemy' in the Bible

because of her afterbirth which hath come out between her feet, and her children whom she shall bear; for she shall secretly eat them for want of everything in the siege and in the straitness wherewith thine enemy shall distress thee in thy gates.

If I did not fear provocation from the enemy, Lest their adversaries should misunderstand it, Lest they should say, Our hand is high, and Jehovah has not done all this.

Mine arrows will I make drunk with blood, And my sword shall devour flesh; I will make them drunk with the blood of the slain and of the captives, With the head of the princes of the enemy.

Thy refuge is the God of old, And underneath are the eternal arms; And he shall drive out the enemy from before thee, And shall say, Destroy them!
