Joshua 18:3-7

so Joshua told the people: The Judah tribe has already settled in its land in the south, and the Joseph tribes have settled in their land in the north. The tribes of Gad, Reuben, and East Manasseh already have the land that the LORD's servant Moses gave them east of the Jordan River. And the people of Levi won't receive land like the other tribes. Instead, they will serve the LORD as priests. But the rest of you haven't done a thing to take over any land. The LORD God who was worshiped by your ancestors has given you the land, and now it's time to go ahead and settle there. Seven tribes still don't have any land. Each of these tribes should choose three men, and I'll send them to explore the remaining land. They will divide it into seven regions, write a description of each region, and bring these descriptions back to me. I will find out from the LORD our God what region each tribe should get.
