Deuteronomy 28:53-55

53“The siege and terrible distress of the enemy’s attack will be so severe that you will eat the flesh of your own sons and daughters, whom the Lord your God has given you.

54The most tenderhearted man among you will have no compassion for his own brother, his beloved wife, and his surviving children.

55He will refuse to share with them the flesh he is devouring—the flesh of one of his own children—because he has nothing else to eat during the siege and terrible distress that your enemy will inflict on all your towns.
