Numbers 36:7

5Moses commanded the children of Israel according to the LORD’s word, saying, “The tribe of the sons of Joseph speak what is right.

6This is the thing which the LORD commands concerning the daughters of Zelophehad, saying, ‘Let them be married to whom they think best, only they shall marry into the family of the tribe of their father.

7So shall no inheritance of the children of Israel move from tribe to tribe; for the children of Israel shall all keep the inheritance of the tribe of his fathers.

8Every daughter who possesses 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 each possess the inheritance of his fathers.

9So shall no inheritance move from one tribe to another tribe; for the tribes of the children of Israel shall each keep his own inheritance.’”
