Joshua 17:12-16
12 Yet the Manassites were not able to occupy these towns, for the Canaanites were determined to live in that region.
13 However, when the Israelites grew stronger, they subjected the Canaanites to forced labor but did not drive them out completely.
14 The people of Joseph said to Joshua, “Why have you given us only one allotment and one portion for an inheritance? We are a numerous people and the Lord has blessed us abundantly.”
15 “If you are so numerous,” Joshua answered, “and if the hill country of Ephraim is too small for you, go up into the forest and clear land for yourselves there in the land of the Perizzites and Rephaites.”
16 The people of Joseph replied, “The hill country is not enough for us, and all the Canaanites who live in the plain have iron chariots, both those in Beth Shan and its settlements and those in the Valley of Jezreel.”
