Numbers 36:5-7

Amplified Bible

⁵ Then Moses commanded the Israelites in accordance with the word of the Lord, saying, “The statement of the tribe of the sons of Joseph is correct. ⁶ This is what the Lord commands regarding the daughters of Zelophehad: ‘Let them marry whom they wish; only they must marry within the family of the tribe of their father.’ ⁷ So no inheritance of the Israelites shall be transferred from tribe to tribe, for every one of the Israelites shall hold to the inheritance of the tribe of his fathers (tribal ancestors).
