When you allocate the land ownership by lot, you are to make a provision for the Lord, a holy allocation of the land that measures 25,000 cubits long and 20,000 cubits wide. This whole area is holy.
Moses, the servant of the Lord, and the Israelites had defeated them, and Moses had allotted the land to the tribes of Reuben, Gad, and the half-tribe of Manasseh.
Moses did not allocate any land for the Levites to own. Instead they were allotted the offerings made by fire to the Lord, the God of Israel, as the Lord had promised them.
The other half of the tribe of Manasseh, and the tribes of Reuben and Gad, had already received their land grant on the east side of the Jordan, as allotted to them by Moses, the servant of the Lord.
