Deuteronomy 28:51

49The LORD shall bring a nation against thee from far, from the end of the earth, as swift as the eagle flieth; a nation whose tongue thou shalt not understand;

50A nation of fierce countenance, which shall not regard the person of the old, nor shew favour to the young:

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 corn, 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 the LORD thy God hath given thee.

53And thou shalt eat the fruit of thine own body, the flesh of thy sons and of thy daughters, which the LORD thy God hath given thee, in the siege, and in the straitness, wherewith thine enemies shall distress thee:
