Numbers 36:8

And every daughter, that possesseth an inheritance in any tribe of the children of Israel, shall be wife unto one of the family of the tribe of her father, that the children of Israel may enjoy every man the inheritance of his fathers.

Numbers 36:8 belongs to the closing instructions of Numbers. Those instructions regulate the marriage of daughters who possess an inheritance, providing that heiresses marry within the family of their father's tribe so that each man of Israel may retain the inheritance of his fathers. They stand together with directions about the cities given to the tribe of Levi and with laws concerning murder.
