'Slope' in the Bible

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.

The border turned about from Baalah westward to Mount Seir, and continued to the slope of Mount Jearim on the north (that is, Chesalon), and went down to Beth-shemesh and continued through Timnah.

The border went down to the edge of the hill which is in the valley of Ben-hinnom, which is in the valley of Rephaim northward; and it went down to the valley of Hinnom, to the slope of the Jebusite southward, and went down to En-rogel.
