2 Samuel 5:8

And David said on that day, Whosoever getteth up to the gutter, and smiteth the Jebusites, and the lame and the blind, that are hated of David’s soul, he shall be chief and captain. Wherefore they said, The blind and the lame shall not come into the house.

The place in view is Jebus, a fortified stronghold held by the Jebusites. It was taken by the Hebrews under the command of Joab, whose valor in the assault was rewarded by making him commander-in-chief of the armies of Israel. After its capture Jebus became the national capital and was renamed Jerusalem.
