Numbers 36:1-3

1And the heads of the fathers’ houses of the family of the children of Gilead, the son of Machir, the son of Manasseh, of the families of the sons of Joseph, came near, and spake before Moses, and before the princes, the heads of the fathers’ houses of the children of Israel:

2and they said, The LORD commanded my lord to give the land for inheritance by lot to the children of Israel: and my lord was commanded by the LORD to give the inheritance of Zelophehad our brother unto his daughters.

3And if they be married to any of the sons of the other tribes of the children of Israel, then shall their inheritance be taken away from the inheritance of our fathers, and shall be added to the inheritance of the tribe whereunto they shall belong: so shall it be taken away from the lot of our inheritance.
