Numbers 36:1-3

1And the chief fathers of families of the sons of Gilead, the son of Machir, the son of Manasseh, of the families of the sons of Joseph, came near, and spoke before Moses, and before the princes, the chief fathers of the children of Israel:

2and they said, Jehovah commanded my lord to give the land for an inheritance by lot to the children of Israel; and my lord was commanded by Jehovah to give the inheritance of Zelophehad our brother to his daughters.

3Now if they be married to any of the sons of the [other] tribes of the children of Israel, then shall their inheritance be taken from the inheritance of our fathers, and shall be added to the inheritance of the tribe to which they shall belong; and it shall be taken from the lot of our inheritance.
