Deuteronomy 28:49-55

49“The Lord will bring a nation against you from far away, from the end of the earth, [as swift] as the eagle swoops down [to attack], a nation whose language you will not understand,

50a defiant nation who will have no respect for the old, nor show favor to the young,

51and it will eat the offspring of your herd and the produce of your ground until you are destroyed, who will leave you no grain, new wine, or oil, nor the offspring of your herd or the young of your flock until they have caused you to perish.

52They will besiege you in all your cities until your high and fortified walls in which you trusted come down throughout your land; and they will besiege you in all your cities throughout your land which the Lord your God has given you.

53Then you will eat the offspring of your own body [to avoid starvation], the flesh of your sons and daughters whom the Lord your God has given you, during the siege and the misery by which your enemy will oppress you.

54The man who is most refined and well-bred among you will be cruel and hostile toward his brother and toward the wife he cherishes and toward the rest of his children who remain,

55so that he will not give even one of them any of the flesh of his children which he will eat, because he has nothing else left, during the siege and the misery by which your enemy will oppress you in all your cities.
