Deuteronomy 28:46-50

And they shall be upon thee for a sign and for a wonder, and upon thy seed for ever.

Because thou servedst not the LORD thy God with joyfulness, and with gladness of heart, for the abundance of all things;

Therefore shalt thou serve thine enemies which the LORD shall send against thee, in hunger, and in thirst, and in nakedness, and in want of all things: and he shall put a yoke of iron upon thy neck, until he have destroyed thee.

The 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;

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