Deuteronomy 28:49-55

49The LORD will bring a nation from afar, from the ends of the earth, to swoop down upon you like an eagle—a nation whose language you will not understand, 50a ruthless nation with no respect for the old and no pity for the young. 51They will eat the offspring of your livestock and the produce of your land until you are destroyed. They will leave you no grain or new wine or oil, no calves of your herds or lambs of your flocks, until they have caused you to perish. 52They will besiege all the cities throughout your land, until the high and fortified walls in which you trust have fallen. They will besiege all your cities throughout the land that the LORD your God has given you.

53Then you will eat the fruit of your womb, the flesh of the sons and daughters whom the LORD your God has given you, in the siege and distress that your enemy will inflict on you.

54The most gentle and refined man among you will begrudge his brother, the wife he embraces,1 and the rest of his children who have survived, 55refusing to share with any of them the flesh of his children he will eat because he has nothing left in the siege and distress that your enemy will inflict on you within all your gates.2
