Numbers 36:6-9

6This is the thing which the LORD doth command concerning the daughters of Zelophehad, saying, Let them marry to whom they think best; only to the family of the tribe of their father shall they marry.1 7So shall not the inheritance of the children of Israel move from tribe to tribe: for every one of the children of Israel shall keep himself to the inheritance of the tribe of his fathers.2 8And every daughter, that possesseth an inheritance in any tribe of the children of Israel, shall be wife to one of the family of the tribe of her father, that the children of Israel may enjoy every man the inheritance of his fathers. 9Neither shall the inheritance move from one tribe to another tribe; but every one of the tribes of the children of Israel shall keep himself to his own inheritance.
