'Top' 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 extended from the top of the mountain to the spring of the waters of Nephtoah and proceeded to the cities of Mount Ephron; then the border curved to Baalah (that is, Kiriath-jearim).
