The meaning of this phrase is not clear. Since there were some Jebusites who survived the battle (see 2 Samuel 24:16–24), we can assume that they were not permitted to enter the city and David’s palace.1 Alternatively, they were banned from the temple (see Leviticus 21:18).2 That the reference is to the Jebusites is made clear from the fact that David received the lame Mephibosheth at his table (2 Samuel 9:3–13).3 He did not have contempt for the lame (or the blind).
8 And David said on that day, “Whoever would strike the Jebusites, let him get up the water shaft to attack ‘the lame and the blind,’ who are hated by David’s soul.” Therefore it is said, “The blind and the lame shall not come into the house.”
