'Blind' in the Bible

The king and his men marched to Jerusalem against the Jebusites who inhabited the land. The Jebusites had said to David: “You will never get in here. Even the blind and lame can repel you”; thinking, “David can’t get in here.”

He said that day, “Whoever attacks the Jebusites must go through the water shaft to reach the lame and the blind who are despised by David.” For this reason it is said, “The blind and the lame will never enter the house.”
