2 Samuel 5:7-9

Living Bible

⁷ But David and his troops defeated them and captured the stronghold of Zion, now called the City of David.

⁸ When the insulting message from the defenders of the city reached David, he told his troops, “Go up through the water tunnel into the city and destroy those ‘lame’ and ‘blind’ Jebusites. How I hate them.” (That is the origin of the saying, “Even the blind and the lame could conquer you!”)

⁹ So David made the stronghold of Zion (also called the City of David) his headquarters. Then, beginning at the old Millo section of the city, he built northward toward the present city center.
