'Blind' in the Bible

And the king and his men went to Jerusalem against the Jebusites, the inhabitants of the land, who spake unto David, saying, Except thou take away the blind and the lame, thou shalt not come in hither; thinking, David cannot come in hither.

And David said on that day, Whosoever smiteth the Jebusites, let him get up to the watercourse, and'smite the lame and the blind, that are hated of David's soul. Wherefore they say, There are the blind and the lame; he cannot come into the house.
