Deuteronomy 28:49-52

49Jehovah will bring a nation against thee from far, from the end of the earth, as the eagle flieth; a nation whose tongue thou shalt not understand; 50a nation of fierce countenance, that shall not regard the person of the old, nor show favor to the young, 51and shall eat the fruit of thy cattle, and the fruit of thy ground, until thou be destroyed; that also shall not leave thee grain, new wine, or oil, the increase of thy cattle, or the young of thy flock, until they have caused thee to perish. 52And they shall besiege thee in all thy gates, until thy high and fortified walls come down, wherein thou trustedst, throughout all thy land; and they shall besiege thee in all thy gates throughout all thy land, which Jehovah thy God hath given thee.
