Deuteronomy 28:28

28 The Lord will afflict you with madness, blindness, and confusion of mind;

Deuteronomy 28:28 In-Context

26 Your corpses shall be food for every bird of the air and animal of the earth, and there shall be no one to frighten them away.
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.
30 You shall become engaged to a woman, but another man shall lie with her. You shall build a house, but not live in it. You shall plant a vineyard, but not enjoy its fruit.
