Deuteronomy 28:49-52

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 language thou shalt not understand;1 50A nation of fierce countenance, which shall not regard the person of the old, nor show favour to the young:2 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.
