Joshua 15:8, 63

and the border went up by the valley of the son of Hinnom unto the side of the Jebusite southward (the same is Jerusalem); and the border went up to the top of the mountain that lieth before the valley of Hinnom westward, which is at the uttermost part of the vale of Rephaim northward

And as for the Jebusites, the inhabitants of Jerusalem, the children of Judah could not drive them out: but the Jebusites dwell with the children of Judah at Jerusalem unto this day.
