Zelophehad was the son of Hepher from the tribe of Manasseh. Zelophehad had five daughters but no sons (Numbers 26:33). Because Zelophehad had no sons, his daughters asked Moses to give them the inheritance of their father (27:1). Moses made a ruling that daughters should receive the inheritance in such cases. But, the daughters must marry men from within their own tribe so that the tribal allotments would remain unchanged (Numbers 27:7; 36:2; Joshua 17:3).
