Joshua 18:4-6
18:4 Pick three men from each tribe. I will send them out to walk through the land and make a map of it for me.
18:5 Divide it into seven regions. Judah will stay in its territory in the south, and the family of Joseph in its territory in the north.
18:6 But as for you, map out the land into seven regions and bring it to me. I will draw lots for you here before the Lord our God.
