Deuteronomy 28:48-57

therefore in hunger and thirst, in nakedness and dire poverty, you will serve the enemies the LORD sends against you. He will put an iron yoke on your neck until he has destroyed you. The LORD will bring a nation against you from far away, from the ends of the earth, like an eagle swooping down, a nation whose language you will not understand, a fierce-looking nation without respect for the old or pity for the young. They will devour the young of your livestock and the crops of your land until you are destroyed. They will leave you no grain, new wine or olive oil, nor any calves of your herds or lambs of your flocks until you are ruined. They will lay siege to all the cities throughout your land until the high fortified walls in which you trust fall down. They will besiege all the cities throughout the land the LORD your God is giving you. Because of the suffering your enemy will inflict on you during the siege, you will eat the fruit of the womb, the flesh of the sons and daughters the LORD your God has given you. Even the most gentle and sensitive man among you will have no compassion on his own brother or the wife he loves or his surviving children, and he will not give to one of them any of the flesh of his children that he is eating. It will be all he has left because of the suffering your enemy will inflict on you during the siege of all your cities. The most gentle and sensitive woman among you—so sensitive and gentle that she would not venture to touch the ground with the sole of her foot—will begrudge the husband she loves and her own son or daughter the afterbirth from her womb and the children she bears. For in her dire need she intends to eat them secretly because of the suffering your enemy will inflict on you during the siege of your cities.
