KJV:
And David said on that day, Whosoever getteth up to the gutter, and smiteth the Jebusites, and the lame and the blind, that are hated of David's soul, he shall be chief and captain. Wherefore they said, The blind and the lame shall not come into the house.
NASB:
David said on that day, "Whoever would strike the Jebusites, let him reach the lame and the blind, who are hated by David's soul, through the water tunnel." Therefore they say, "The blind or the lame shall not come into the house."
