Numbers 36:6-8

New Revised Standard Version Catholic Edition

⁶ This is what the Lord commands concerning the daughters of Zelophehad, ‘Let them marry whom they think best; only it must be into a clan of their father’s tribe that they are married, ⁷ so that no inheritance of the Israelites shall be transferred from one tribe to another; for all Israelites shall retain the inheritance of their ancestral tribes. ⁸ Every daughter who possesses an inheritance in any tribe of the Israelites shall marry one from the clan of her father’s tribe, so that all Israelites may continue to possess their ancestral inheritance.
