Joshua 15:8, 63

Then the border went up by the Valley of Ben-hinnom (son of Hinnom) at the southern slope of the Jebusite [city] (that is, Jerusalem); and the border went up to the top of the mountain that lies before the Valley of Hinnom to the west, which is at the northern end of the Valley of Rephaim.

But as for the Jebusites, the inhabitants of Jerusalem, the [tribe of the] sons of Judah were not able to drive them out; so the Jebusites live with the sons of Judah in Jerusalem to this day.
