Deuteronomy 28:27-29

The LORD will punish you with boils like those the Egyptians had. You will have bad growths, sores, and itches that can’t be cured. The LORD will give you madness, blindness, and a confused mind. You will have to feel around in the daylight like a blind person. You will fail in everything you do. People will hurt you and steal from you every day, and no one will save you.
