'Blind and the Lame' in the Bible

And the king and his men went to Jerusalem unto the Jebusites, the inhabitants of the land: who spoke unto David, saying, Except you take away the blind and the lame, you shall not come in here: thinking, David cannot come in here.

And David said on that day, Whosoever gets up the water shaft, and strikes the Jebusites, and the lame and the blind, that are hated of David's soul, he shall be chief and captain. Therefore they said, The blind and the lame shall not come into the house.
