Numbers 36:6-8

BSB(i) 6 This is what the LORD has commanded concerning the daughters of Zelophehad: They may marry anyone they please, provided they marry within a clan of the tribe of their father. 7 No inheritance in Israel may be transferred from tribe to tribe, because each of the Israelites is to retain the inheritance of the tribe of his fathers. 8 Every daughter who possesses an inheritance from any Israelite tribe must marry within a clan of the tribe of her father, so that every Israelite will possess the inheritance of his fathers.
