Numbers 36:2-3

36:2 They said, “The Lord commanded my lord to give the land as an inheritance by lot to the Israelites; and my lord was commanded by the Lord to give the inheritance of our brother Zelophehad to his daughters. 36:3 Now if they should be married to one of the men 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. As a result, it will be taken from the lot of our inheritance.
