Tirzah was one of the daughters of Zelophehad from the tribe of Manasseh (Numbers 26:33). Since her father had no sons, she and her sisters asked for and received the inheritance of their father (Numbers 27:1; Joshua 17:3). This situation led to the creation of a new law about inheritance rights. The law stated that daughters who received their families' inheritance must marry someone from within their own tribe (Numbers 36:11).
