Deuteronomy 28:47-50

48thou shalt serve thine enemies whom Jehovah will send against thee, in hunger, and in thirst, and in nakedness, and in want of everything; and he shall put a yoke of iron upon thy neck, until he have destroyed thee.

49Jehovah will bring a nation against thee from afar, from the end of the earth, like as the eagle flieth, a nation whose tongue thou understandest not;

50a nation of fierce countenance, which regardeth not the person of the old, nor is kind to the young;
