Joshua 16

5 Now this was the territory of the sons of Ephraim according to their families: the border of their inheritance eastward was aAtaroth-addar, as far as upper Beth-horon.
6 Then the border went westward at aMichmethath on the north, and the border turned about eastward to Taanath-shiloh and continued beyond it to the east of Janoah.
7 It went down from Janoah to Ataroth and to aNaarah, then reached Jericho and came out at the Jordan.
8 From aTappuah the border continued westward to the brook of Kanah, and it ended at the sea. This is the inheritance of the tribe of the sons of Ephraim according to their families,
9 together with the cities which were set apart for the sons of Ephraim in the midst of the inheritance of the sons of Manasseh, all the cities with their villages.

Joshua 17

8 The land of Tappuah belonged to Manasseh, but aTappuah on the border of Manasseh belonged to the sons of Ephraim.
9 The aborder went down to the brook of Kanah, southward of the brook (these cities belonged to Ephraim among the cities of Manasseh), and the border of Manasseh was on the north side of the brook and it ended at the sea.
10 The south side belonged to Ephraim and the north side to Manasseh, and the sea was their border; and they reached to Asher on the north and to Issachar on the east.

Joshua 17

14 Then the asons of Joseph spoke to Joshua, saying, "Why have you given me only one lot and one portion for an inheritance, since I am a numerous people whom the Lord has thus far blessed?"
15 Joshua said to them, "If you are a numerous people, go up to the forest and clear a place for yourself there in the land of the Perizzites and of the Rephaim, since the hill country of Ephraim is too narrow for you."
16 The sons of Joseph said, "The hill country is not enough for us, and all the Canaanites who live in the valley land have achariots of iron, both those who are in Beth-shean and its towns and those who are in the valley of Jezreel."
17 Joshua spoke to the house of Joseph, to Ephraim and Manasseh, saying, "You are a numerous people and have great power; you shall not have one lot only,
18 but the hill country shall be yours. For though it is a forest, you shall clear it, and to its farthest borders it shall be yours; for you shall drive out the Canaanites, even though they have achariots of iron and though they are strong."
