Numbers 18:26

Numbers 27:11

27:11 and if his father has no brothers, then you are to give his inheritance to his relative nearest to him from his family, and he will possess it. This will be for the Israelites a legal requirement, as the Lord commanded Moses.’”

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.
