Deuteronomy 28:27-29

New Revised Standard Version, Anglicised Catholic Edition

²⁷ The Lord will afflict you with the boils of Egypt, with ulcers, scurvy, and itch, of which you cannot be healed. ²⁸ The Lord will afflict you with madness, blindness, and confusion of mind; ²⁹ you shall grope about at noon as blind people grope in darkness, but you shall be unable to find your way; and you shall be continually abused and robbed, without anyone to help.
