Numbers 36:2-6

and they said, “The Lord commanded my lord 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 our brother Zelophehad to his daughters.

But if they marry one of the sons of the other tribes of the sons of Israel, their inheritance will be withdrawn from the inheritance of our fathers and will be added to the inheritance of the tribe to which they belong; so it will be withdrawn from our allotted inheritance.

And when the jubilee of the sons of Israel takes place, then their inheritance will be added to the inheritance of the tribe to which they belong; so their inheritance will be withdrawn from the inheritance of the tribe of our fathers.”

Then Moses commanded the sons of Israel in accordance with the word of the Lord, saying, “The tribe of the sons of Joseph is right in its statements.

This is what the Lord has commanded regarding the daughters of Zelophehad, saying, ‘Let them marry whomever they wish; only they must marry within the family of the tribe of their father.’
