Deuteronomy 28:53-57

Then you shall eat the offspring of your own body, the flesh of your sons and of your daughters whom the LORD your God has given you, during the siege and the distress by which your enemy will oppress you. The man who is refined and very delicate among you shall be hostile toward his brother and toward the wife he cherishes and toward the rest of his children who remain, so that he will not give even one of them any of the flesh of his children which he will eat, since he has nothing else left, during the siege and the distress by which your enemy will oppress you in all your towns. The refined and delicate woman among you, who would not venture to set the sole of her foot on the ground for delicateness and refinement, shall be hostile toward the husband she cherishes and toward her son and daughter, and toward her afterbirth which issues from between her legs and toward her children whom she bears; for she will eat them secretly for lack of anything else, during the siege and the distress by which your enemy will oppress you in your towns.
