Deuteronomy 28:51-52

51and he shall eat the fruit of thy cattle, and the fruit of thy ground, until thou be destroyed: which also shall not leave thee corn, wine, or oil, the increase of thy kine, or the young of thy flock, until he have caused thee to perish.

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 the LORD thy God hath given thee.
