Deuteronomy 28:43-48

The stranger that is within thee shall get up above thee very high; and thou shalt come down very low. He shall lend to thee, and thou shalt not lend to him: he shall be the head, and thou shalt be the tail. Moreover all these curses shall come upon thee, and shall pursue thee, and overtake thee, till thou be destroyed; because thou hearkenedst not unto the voice of the LORD thy God, to keep his commandments and his statutes which he commanded thee: 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.
