Deuteronomy 28:52-53

52“They shall besiege you at all your gates until your high and fortified walls, in which you trust, come down throughout all your land; and they shall besiege you at all your gates throughout all your land which the Lord your God has given you.

53You shall eat the fruit of your own body, the flesh of your sons and your daughters whom the Lord your God has given you, in the siege and desperate straits in which your enemy shall distress you.
