Leviticus 26:26-29

26I will destroy your food supply, so that ten women will need only one oven to bake bread for their families. They will ration your food by weight, and though you have food to eat, you will not be satisfied.

27“If in spite of all this you still refuse to listen and still remain hostile toward me,

28then I will give full vent to my hostility. I myself will punish you seven times over for your sins.

29Then you will eat the flesh of your own sons and daughters.
