Deuteronomy 28:53-55

53“You will eat your offspring, the flesh of your sons and daughters the Lord your God has given you during the siege and hardship your enemy imposes on you.

54The most sensitive and refined man among you will look grudgingly at his brother, the wife he embraces, and the rest of his children,

55refusing to share with any of them his children’s flesh that he will eat because he has nothing left during the siege and hardship your enemy imposes on you in all your towns.
