Deuteronomy 28:52-53

52"They shall besiege you in all your towns, until your high and fortified walls, in which you trusted, come down throughout all your land. And they shall besiege you in all your towns throughout all your land, which the Lord your God has given you.

53And you shall eat the fruit of your womb, the flesh of your sons and daughters, whom the Lord your God has given you, in the siege and in the distress with which your enemies shall distress you.
