Deuteronomy 28:53-55

53Then you will eat the fruit of your womb, the flesh of the sons and daughters whom the LORD your God has given you, in the siege and distress that your enemy will inflict on you.

54The most gentle and refined man among you will begrudge his brother, the wife he embraces,1 and the rest of his children who have survived, 55refusing to share with any of them the flesh of his children he will eat because he has nothing left in the siege and distress that your enemy will inflict on you within all your gates.2
