2 Samuel 5:5-9

5In Hebron he reigned over Judah seven years and six months, and in Jerusalem he reigned thirty-three years over all Israel and Judah.

6And the king and his men went to Jerusalem against the Jebusites, the inhabitants of the land, who spoke to David, saying, “You shall not come in here; but the blind and the lame will repel you,” thinking, “David cannot come in here.”

7Nevertheless David took the stronghold of Zion (that is, the City of David).

8Now David said on that day, “Whoever climbs up by way of the water shaft and defeats the Jebusites (the lame and the blind, who are hated by David’s soul), he shall be chief and captain.” Therefore they say, “The blind and the lame shall not come into the house.”

9Then David dwelt in the stronghold, and called it the City of David. And David built all around from the Millo and inward.
