Joshua 18:3-7

So Joshua said to the sons of Israel, “How long will you put off entering to take possession of the land which the Lord, the God of your fathers, has given you?

Provide for yourselves three men from each tribe so that I may send them, and that they may arise and walk through the land and write a description of it according to their inheritance; then they shall return to me.

And they shall divide it into seven portions; Judah shall stay in its territory on the south, and the house of Joseph shall stay in their territory on the north.

And you shall write a description of the land in seven divisions, and bring the description here to me. Then I will cast lots for you here before the Lord our God.

For the Levites have no portion among you, because the priesthood of the Lord is their inheritance. Gad, Reuben, and the half-tribe of Manasseh also have received their inheritance eastward beyond the Jordan, which Moses the servant of the Lord gave them.”
