Deuteronomy 28:52-53

52They will besiege all the cities throughout your land, until the high and fortified walls in which you trust have fallen. They will besiege all your cities throughout the land that the LORD your God has given you.

53Then you will eat the fruit of your womb, the flesh of the sons and daughters whom the LORD your God has given you, in the siege and distress that your enemy will inflict on you.
