'Valley of Hinnom' in the Bible

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.

Then the border went down to the edge of the hill overlooking the Valley of Ben-hinnom (son of Hinnom), which is at the north end of the Valley of Rephaim; and it descended to the Valley of Hinnom, south to the slope of the Jebusite, and went on down to En-rogel.
