'Blindness' in the Bible

And they smote the men that were at the door of the house with blindness, both small and great: so that they wearied themselves to find the door.

The LORD shall smite thee with madness, and blindness, and astonishment of heart:

And when they came down to him, Elisha prayed unto the LORD, and said, Smite this people, I pray thee, with blindness. And he smote them with blindness according to the word of Elisha.

In that day, saith the LORD, I will smite every horse with astonishment, and his rider with madness: and I will open mine eyes upon the house of Judah, and will smite every horse of the people with blindness.
