'Blind and the Lame' in the Bible

And the king and his men went to Jerusalem to the Jebusites, the inhabitants of the land: who spoke to David, saying, Except thou shalt 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, Whoever getteth up to the gutter, and smiteth the Jebusites, and the lame and the blind, that are hated by David's soul, he shall be chief and captain: Wherefore they said, The blind and the lame shall not come into the house.
