Joshua 18:2-6

And there remained among the children of Israel seven tribes, which had not yet received their inheritance.

And Joshua said unto the children of Israel, How long are ye slack to go to possess the land, which the LORD God of your fathers hath given you?

Give out from among you three men for each tribe: and I will send them, and they shall rise, and go through the land, and describe it according to the inheritance of them; and they shall come again to me.

And they shall divide it into seven parts: Judah shall abide in their coast on the south, and the house of Joseph shall abide in their coasts on the north.

Ye shall therefore describe the land into seven parts, and bring the description hither to me, that I may cast lots for you here before the LORD our God.
