Deuteronomy 28:51-52

51And he shall eat the fruit of thy cattle, and the fruit of thy land, until thou be destroyed: which also shall not leave thee either grain, wine, or oil, or the increase of thy kine, or flocks of thy sheep, until he have destroyed thee.

52And he shall besiege thee in all thy gates, until thy high and fenced walls come down, wherein thou trustedst, throughout all thy land: and he shall besiege thee in all thy gates throughout all thy land, which Yhwh thy God hath given thee.
