Deuteronomy 28:54-55

The man who is the most tender and refined among you will begrudge food to his brother, to the wife he embraces, and to the last of the children whom he has left, so that he will not give to any of them any of the flesh of his children whom he is eating, because he has nothing else left, in the siege and in the distress with which your enemy shall distress you in all your towns.
