Numbers 33:54

33:54 You must divide the land by lot for an inheritance among your families. To a larger group you must give a larger inheritance, and to a smaller group you must give a smaller inheritance. Everyone’s inheritance must be in the place where his lot falls. You must inherit according to your ancestral ¹  tribes.

Numbers 35:8

35:8 The towns you will give must be from the possession of the Israelites. From the larger tribes you must give more; and from the smaller tribes fewer. Each must contribute some of its own towns to the Levites in proportion to the inheritance allocated to each.
