Joshua 18:5-7
5
They shall divide it into seven portions. Judah shall live in his borders on the south, and the house of Joseph shall live in their borders on the north.
6
You shall survey the land into seven parts, and bring the description here to me; and I will cast lots for you here before Yahweh our God.
7
For the Levites have no portion among you; for the priesthood of Yahweh is their inheritance. Gad, Reuben, and the half-tribe of Manasseh have received their inheritance beyond the Jordan eastward, which Moses the servant of Yahweh gave them."
