2 Samuel 5:7-9

VIN(i) 7 David captured the fortress of Zion, the city of David. 8 At that time, David had said, "Whoever intends to attack the Jebusites will have to climb up the water shaft to attack the lame and blind, who hate David." Therefore they say, "The blind and lame shall never come into the house." 9 David occupied the fortress, naming it the City of David. He built up the surroundings from the terrace ramparts inward.
