Deuteronomy 28:51-52

51And he shall eat the fruit of thy cattle, and the fruit of thy land, until thou art destroyed: which also shall not leave thee either grain, wine, or oil, or the increase of thy cattle, or flocks of thy sheep, until he hath destroyed thee. 52And he shall besiege thee in all thy gates, until thy high and fortified walls come down, in which thou didst trust, throughout all thy land: and he shall besiege thee in all thy gates throughout all thy land, which the LORD thy God hath given thee.
