Deuteronomy 28:49-55

49The 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,

50a fierce-looking nation without respect for the old or pity for the young.

51They 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.

52They 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.

53Because 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.

54Even 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,

55and 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.
