'Grazing' in the Bible
Now, the descendants of Reuben and descendants of Gad happened to be joint owners of a very large herd of cattle. When they observed that Jazer and Gilead were good grazing lands for cattle,
"Instruct the Israelis to set aside a portion of their inheritance for the descendants of Levi to live in, along with grazing land surrounding their towns.
The towns are to be reserved for their dwelling places and the grazing lands are to be reserved for their cattle, livestock, and all their animals.
The grazing lands that you are to reserve for use by the descendants of Levi are to extend 1,000 cubits from the walls of the town.
You are to measure from outside the wall of the town on the east side 2,000 cubits, on the south side 2,000 cubits, on the west side 2,000 cubits, and on the north side 2,000 cubits, with the town placed at the center. This reserved area is to serve as grazing land for their towns.
The total number of towns that you are to give to the descendants of Levi is to be 48 towns, including grazing lands surrounding these towns.
