Joshua 16:3-7

Then it went down westward to the territory of the Japhletites, as far as the territory of lower Beth-horon even to Gezer, and it ended at the sea.

The sons of Joseph, Manasseh and Ephraim, received their inheritance.

Now this was the territory of the sons of Ephraim according to their families: the border of their inheritance eastward was Ataroth-addar, as far as upper Beth-horon.

Then the border went westward at Michmethath on the north, and the border turned eastward to Taanath-shiloh and continued beyond it to the east of Janoah.

Then it went down from Janoah to Ataroth and to Naarah, then reached Jericho and came out at the Jordan.
