Joshua 17:14-18 - The Tribes Of Joseph Object
14 The children of Joseph spoke to Joshua, saying, "Why have you given me just one lot and one part for an inheritance, since I am a great people, because Yahweh has blessed me so far?"
15 Joshua said to them, "If you are a great people, go up to the forest, and clear land for yourself there in the land of the Perizzites and of the Rephaim; since the hill country of Ephraim is too narrow for you."
16 The children of Joseph said, "The hill country is not enough for us. All the Canaanites who dwell in the land of the valley have chariots of iron, both those who are in Beth Shean and its towns, and those who are in the valley of Jezreel."
17 Joshua spoke to the house of Joseph, even to Ephraim and to Manasseh, saying, "You are a great people, and have great power. You shall not have one lot only; 18 but the hill country shall be yours. Although it is a forest, you shall cut it down, and it's farthest extent shall be yours; for you shall drive out the Canaanites, though they have chariots of iron, and though they are strong."
