Joshua 17:12-18

12 But the people of Manasseh weren't able to take over those towns. That's because the people of Canaan had made up their minds to live in that area.
13 The people of Israel grew stronger. Then they forced the people of Canaan to work hard for them. But they didn't drive them out completely.
14 The people in the family line of Joseph spoke to Joshua. They said, "Why have you given us only one share of the land to have as our own? There are large numbers of us. The LORD has blessed us greatly."
15 "That's true," Joshua said. "There are large numbers of you. And the hill country of Ephraim is too small for you. So go up into the forest. Clear out some land for yourselves in the territory of the Perizzites and Rephaites."
16 The people in Joseph's family line replied. They said, "The hill country isn't big enough for us. And all of the people of Canaan who live in the flatlands use chariots that have iron parts. They include the people of Beth Shan and its settlements. They also include the people who live in the Valley of Jezreel."
17 Joshua spoke again to the people in Joseph's family line. He said to the people of Ephraim and Manasseh, "There are large numbers of you. And you are very powerful. You will have more than one piece of land.
18 You will also have the central hill country. It's covered with trees. Cut them down and clear the land. That whole land from one end to the other will belong to you. The people of Canaan use chariots that have iron parts. And those people are strong. But you can drive them out."
