Joshua 17:14-18 - The Tribes Of Joseph Object
14 At that time, the descendants of Joseph asked Joshua, "Why did you give us only one allotment and portion for an inheritance, since we're numerous and the LORD has blessed us all along?"
15 So Joshua replied to them, "Since you're so numerous, go up to the forest and clear ground there for yourselves in the territory where the Perizzites and Rephaim are, because the hill country of Ephraim is too narrow for you."
16 The descendants of Joseph replied, "The hill country isn't sufficient for us, but all the Canaanites who live on the plain have iron chariots, both those in Beth-shean and its villages as well as the inhabitants of the Jezreel Valley."
17 So Joshua told the tribes of Joseph, which were Ephraim and Manasseh, "You're truly a numerous group, and you have great power. You are not to have only one allotment, 18 but the hill country will also belong to you. Even though it's a forest, you will clear it and possess it to its farthest borders. You'll drive out the Canaanites, even though they have iron chariots and even though they're strong."
