'Northern' in the Bible

The eastern border was the Salt (Dead) Sea, as far as the mouth of the Jordan. The northern border was from the bay of the sea at the mouth of the Jordan.

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.

The border went around west from Baalah to Mount Seir, and passed along to the northern slope of Mount Jearim (that is, Chesalon), and went down to Beth-shemesh and then continued on through Timnah.

The border continued along to the north of the slope of Beth-hoglah; and the border ended at the northern bay of the Salt (Dead) Sea, at the south end of the Jordan. This was the southern border.
