Deuteronomy 28:49-53

ISV^{(i) 49} “The LORD will raise a distant nation against you from the other side of the earth. Swooping down like a vulture, ⁵⁰ it will be a nation whose language you don’t understand, whose stern appearance neither shows regard nor extends grace to anyone whether old or young. ⁵¹ Its army will consume the offspring of your animals and the produce of your soil until you are exterminated. They will leave you without your grain, wine, oil, the increase of your cattle, and the lamb of your flock, until you are completely destroyed. ⁵² They’ll besiege all your cities until your high and fortified walls in which you have trusted collapse throughout the land. Indeed, they will besiege all your cities, which the LORD your God gave you.”
⁵³ Cannibalism“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.
