Numbers 36:1-3

1The leaders of the fathers’ households of the family of the sons of Gilead, the son of Machir, the son of Manasseh, of the families of the sons of Joseph, approached and spoke before Moses and before the leaders, the heads of the fathers’ households of the Israelites,

2and they said, “The Lord commanded my lord [Moses] to give the land by lot to the sons of Israel as an inheritance, and my lord was commanded by the Lord to give the inheritance of Zelophehad our brother to his daughters.

3But if the daughters marry any of the men from any of the other tribes of Israel, then their inheritance will be taken away from that of our fathers (tribal ancestors) and will be added to the inheritance of the tribe to which they belong; so it will be taken away from our allotted inheritance.
