Numbers 36:6-8

Amplified Bible, Classic Edition

⁶ This is what the Lord commands concerning the daughters of Zelophehad: Let them marry whom they think best; only they shall marry within the family of the tribe of their father.

⁷ So shall no inheritance of the Israelites be transferred from tribe to tribe, for every one of the Israelites shall cling to the inheritance of the tribe of his fathers.

⁸ And every daughter who possesses an inheritance in any tribe of the Israelites shall be wife to one of the family of the tribe of her father, so that the Israelites may each one possess the inheritance of his fathers.
