Deuteronomy 28:51-52

51and he shall eat the fruit of thy cattle, and the fruit of thy ground, until thou be destroyed; for he shall not leave thee corn, new wine, or oil, offspring of thy kine, or increase of thy sheep, until he have destroyed thee.

52And he shall besiege thee in all thy gates, until thy high and strong walls wherein thou trustedst come down, throughout all thy land; and he shall besiege thee in all thy gates in all thy land, which Jehovah thy 1God hath given thee.
