'Blind' in the Bible

And the king and his men went to Jerusalem against the Jebusites, the people of the land: and they said to David, You will not come in here, but the blind and the feeble-footed will keep you out; for they said, David will not be able to come in here.

And that day David said, Whoever makes an attack on the Jebusites, let him go up by the water-pipe, and put to death all the blind and feeble-footed who are hated by David. And this is why they say, The blind and feeble-footed may not come into the house.
