Numbers 26:53-57

“Among these the land shall be divided as an inheritance according to the number of names.

To a larger group you shall increase their inheritance, and to a smaller group you shall decrease their inheritance; each shall be given their inheritance corresponding to the total of those who were numbered of them.

But the land shall be divided by lot. They shall receive their inheritance according to the names of the tribes of their fathers.

Corresponding to the selection by lot, their inheritance shall be divided between the larger and the smaller groups.”

These are those who were numbered of the Levites according to their families: of Gershon, the family of the Gershonites; of Kohath, the family of the Kohathites; of Merari, the family of the Merarites.
