Numbers 36:7-9

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.1 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.
