2 Samuel 5:1-10

Then all the tribes of Israel came to David at Hebron and said, “Behold, we are your bone and your flesh. In times past, when Saul was king over us, it was you who led Israel out [to war] and brought Israel in [from battle]. And the LORD told you, ‘You shall shepherd My people Israel and be ruler over them.’ ” [1 Sam 15:27-29; 16:1] So all the elders (tribal leaders) of Israel came to the king at Hebron, and King David made a covenant with them at Hebron before the LORD; and they anointed him king over Israel. David was thirty years old when he became king, and he reigned forty years. In Hebron he reigned over Judah seven years and six months, and in Jerusalem he reigned thirty-three years over all Israel and Judah. Now the king and his men went to Jerusalem against the Jebusites, the inhabitants of the land, who said to David, “You shall not enter here, for the blind and the lame [even the weakest among us] will turn you away”; they thought, “David cannot come in here [because the walls are impenetrable].” Nevertheless, David captured the stronghold (fortress) of Zion, that is, the City of David. Then David said on that day, “Whoever strikes the Jebusites, let him go up through the [underground] water shaft to strike the lame and the blind, who are detested by David’s soul [because of their arrogance].” So [for that reason] they say, “The blind or the lame (Jebusites) shall not come into the [royal] house [of Israel].” [1 Chr 11:6] So David lived in the stronghold and called it the City of David. And he built all around [the surrounding area] from the Millo [fortification] and inward. David became greater and greater, for the LORD, the God of hosts (armies), was with him.
