Deuteronomy 28:53-55

New International Version - UK

⁵³ 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. ⁵⁴ 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, ⁵⁵ 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 that your enemy will inflict on you during the siege of all your cities.
