2 Samuel 5:8-10

Complete Jewish Bible

⁸ What David said on that day was, “In order to attack the Y’vusi, you have to climb up [from the spring outside the city] through the water tunnel. Then you can do away with those [so-called] ‘lame and blind’” (whom David despises — hence the expression, “The ‘blind and lame’ keep him from entering the house”).

⁹ David lived in the stronghold and called it the City of David. Then David built up the city around it, starting at the Millo [earth rampart] and working inward. ¹⁰ David grew greater and greater, because Adonai the God of Armies was with him.
