12 The sons of Manasseh were not able to overthrow these cities, and so the Canaanite began to dwell in their land.
13 But after the sons of Israel had grown strong, they subdued the Canaanites, and made them their tributaries, but they did not kill them.
14 And the sons of Joseph spoke to Joshua, and they said, "Why have you given to me as a possession one lot and one portion, while I am of such a great multitude, and the Lord has blessed me?"
15 And Joshua said to them, "If you are a numerous people, go up into the forest, and cut out space for yourself in the land of the Perizzites and the Rephaim, since the possession of mount Ephraim is too narrow for you."
16 And the sons of Joseph responded to him: "We are not able to ascend to the mountains, since the Canaanites, who live in the plains, in which are situated Bethshean, with its villages, and Jezreel, possessing the middle of the valley, use chariots of iron."
17 And Joshua said to the house of Joseph, to Ephraim and Manasseh: "You are a numerous people, and you have great strength. You shall not have only one lot.
18 Instead, you shall cross to the mountain, and you shall cut down and clear out for yourselves space in which to live. And you shall be able to advance further, when you will have destroyed the Canaanite, who, as you say, has iron chariots and is very strong."
