Numbers 36:4-6

American Standard Version

⁴ And when the jubilee of the children of Israel shall be, then will their inheritance be added unto the inheritance of the tribe whereunto they shall belong: so will their inheritance be taken away from the inheritance of the tribe of our fathers.

⁵ And Moses commanded the children of Israel according to the word of Jehovah, saying, The tribe of the sons of Joseph speaketh right. ⁶ This is the thing which Jehovah doth command concerning the daughters of Zelophehad, saying, Let them be married to whom they think best; only into the family of the tribe of their father shall they be married.
