Joshua 15:8, 63

Then the border went up the valley of Ben-hinnom to the slope of the Jebusite on the south (that is, Jerusalem); and the border went up to the top of the mountain which is before the valley of Hinnom to the west, which is at the end of the valley of Rephaim toward the north.

Now as for the Jebusites, the inhabitants of Jerusalem, the sons of Judah could not drive them out; so the Jebusites live with the sons of Judah at Jerusalem until this day.
