'Enemy' in the Bible

When thou goest out to battle against thine enemy, and hast seen horse and chariot -- a people more numerous than thou -- thou art not afraid of them, for Jehovah thy God is with thee, who is bringing thee up out of the land of Egypt;

against giving to one of them of the flesh of his sons whom he eateth, because he hath nothing left to him, in the siege, and in the straitness with which thine enemy doth straiten thee in all thy gates.

and against her seed which cometh out from between her feet, even against her sons whom she doth bear, for she doth eat them for the lacking of all things in secret, in the siege and in the straitness with which thine enemy doth straiten thee within thy gates.

If not -- the anger of an enemy I fear, Lest their adversaries know -- Lest they say, Our hand is high, And Jehovah hath not wrought all this.

I make drunk Mine arrows with blood, And My sword devoureth flesh, From the blood of the pierced and captive, From the head of the freemen of the enemy.

A habitation is the eternal God, And beneath are arms age-during. And He casteth out from thy presence the enemy, and saith, 'Destroy!'
