Joshua 16:1-4

Then the lot (allotment) for the sons of Joseph went from the Jordan Valley at Jericho to the waters of Jericho on the east into the wilderness, going up from Jericho through the hill country to Bethel. Then it went from Bethel to Luz, and continued to Ataroth, the border of the Archites. It went down westward to the territory of the Japhletites, as far as the outskirts of lower Beth-horon, then to Gezer, and it ended at the sea. The sons of Joseph, Manasseh and Ephraim, received their inheritance.
