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.

Numbers 36:3

36:3 Now if they should be married to one of the men ¹  from another Israelite tribe, their inheritance would be taken from the inheritance of our fathers and added to the inheritance of the tribe into which they marry. ²  As a result, it will be taken from the lot of our inheritance.

[36:3]  ¹ tn “Men” is understood; it says “to one from the sons of the tribes of the Israelites for a wife,” or if he has her for a wife.

[36:3]  ² tn Heb “which they will be to them,” meaning, to those who have them, i.e., the marriages.
