Deuteronomy 28:53-57

Then you will eat the offspring of your own body [to avoid starvation], the flesh of your sons and daughters whom the LORD your God has given you, during the siege and the misery by which your enemy will oppress you. [2 Kin 6:24-29] The man who is most refined and well-bred among you will be cruel and 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, because he has nothing else left, during the siege and the misery by which your enemy will oppress you in all your cities. The most refined and well-bred woman among you, who would not venture to set the sole of her foot on the ground because she is so delicate and pampered, will be cruel and hostile toward the husband she cherishes and toward her son and daughter, and toward her afterbirth that comes from between her legs and toward the children whom she bears; for she will eat them secretly for lack of anything else, during the siege and the misery by which your enemy will oppress you in your cities.
