'Enemy' in the Bible

"You'll eat your own children the flesh of your sons and daughters, whom the LORD your God gave you on account of the siege and the distress with which your enemy will oppress you.

He will withhold from each of them the flesh of his sons that he is eating since there will be nothing left on account of the siege and distress with which your enemy will oppress you in all your cities.

She will eat her afterbirth and her newborn children secretly since there will be nothing left on account of the siege and distress with which your enemy will oppress you in your cities."

I'll make my arrows drunk with blood. My sword will devour flesh, along with the blood of the slain, and I'll take their enemy leaders captive.'
