Deuteronomy 28 28
The Lord shall smite thee with madness, and blindness, and astonishment of heart:
And they struck with blindness the men at the entrance, both young and old so that they were unable to find the door. They wandered blind in the streets, defiled by this blood so that no one dared to touch their garments.
Thou hast shewed thy people hard things: thou hast made us to drink the wine of astonishment. But the Spirit of the LORD departed from Saul, and an evil spirit from the LORD troubled him.
