Joshua 17:12-18

12But the men of Manasseh were unable to conquer these cities; the Canaanites managed to remain in those areas.

13Whenever the Israelites were strong militarily, they forced the Canaanites to do hard labor, but they never totally conquered them.

14The descendants of Joseph said to Joshua, “Why have you assigned us only one tribal allotment? After all, we have many people, for until now the Lord has enabled us to increase in number.”

15Joshua replied to them, “Since you have so many people, go up into the forest and clear out a place to live in the land of the Perizzites and Rephaites, for the hill country of Ephraim is too small for you.”

16The descendants of Joseph said, “The whole hill country is inadequate for us, and the Canaanites living down in the valley in Beth Shean and its surrounding towns and in the Valley of Jezreel have chariots with iron-rimmed wheels.”

17Joshua said to the family of Joseph – to both Ephraim and Manasseh: “You have many people and great military strength. You will not have just one tribal allotment.

18The whole hill country will be yours; though it is a forest, you can clear it and it will be entirely yours. You can conquer the Canaanites, though they have chariots with iron-rimmed wheels and are strong.”
