Deuteronomy 28:27-29

Jehovah will smite thee with the boil of Egypt, and with the emerods, and with the scurvy, and with the itch, whereof thou canst not be healed. Jehovah will smite thee with madness, and with blindness, and with astonishment of heart; and thou shalt grope at noonday, as the blind gropeth in darkness, and thou shalt not prosper in thy ways: and thou shalt be only oppressed and robbed alway, and there shall be none to save thee.
