Deuteronomy 28:52-53

52They will attack all your towns, everywhere in the land that the Lord your God has given to you. They will knock down the strong walls that you thought would keep you safe. They will make their camps around your towns until they can take the towns for themselves.

53When that happens, you will have no food, because your enemy's soldiers are all around your town. You will be so hungry that you eat your own children. Those are the sons and daughters that the Lord your God has given to you.
