Deuteronomy 28:51-55

Furthermore, it will eat the offspring of your herd and the produce of your ground until you are destroyed; a nation that will leave you no grain, new wine, or oil, nor the newborn of your cattle or the young of your flock, until they have eliminated you.

And it will besiege you in all your towns until your high and fortified walls in which you trusted come down throughout your land, and it will besiege you in all your towns throughout your land which the Lord your God has given you.

Then you will eat the offspring of your own body, the flesh of your sons and of your daughters whom the Lord your God has given you, during the siege and the hardship by which your enemy will oppress you.

The man who is refined and very delicate among you will be hostile toward his brother, toward the wife he cherishes, and toward the rest of his children who are left,

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