Joshua 17:12, 16-18

Yet the men of Manasseh failed to take possession of those towns, and the Canaanites continued to live in that land.

The descendants of Joseph answered, “Indeed, there’s not enough room for us in the hill country of Ephraim. Yet all the Canaanites who live in the plain have chariots with iron-rimmed wheels, both those in Beth Shean and its villages, and those in the Valley of Jezreel.” Then Joshua said to the tribe of Ephraim and the half-tribe of Manasseh, “There are indeed many people in your tribes, and for that reason, you are very powerful. I will give you more than one share of land. Therefore, I will give you the hill country as well. It is a forest, but YAHWEH will empower you to take possession of it and clear it from one end to the other. You will conquer all the Canaanites even though they not only have iron chariots but also are a strong people.”
