The previous reference of the daughters of Zelophehad, in Numbers 27 (Num 27:1-111Then the daughters of Zelophehad, the son of Hepher, the son of Gilead, the son of Machir, the son of Manasseh, of the families of Manasseh the son of Joseph, came near; and these are the names of his daughters: Mahlah, Noah and Hoglah and Milcah and Tirzah.2They stood before Moses and before Eleazar the priest and before the leaders and all the congregation, at the doorway of the tent of meeting, saying,3“Our father died in the wilderness, yet he was not among the company of those who gathered themselves together against the LORD in the company of Korah; but he died in his own sin, and he had no sons.4Why should the name of our father be withdrawn from among his family because he had no son? Give us a possession among our father’s brothers.”5So Moses brought their case before the LORD.6Then the LORD spoke to Moses, saying,7“The daughters of Zelophehad are right in [their] statements. You shall surely give them a hereditary possession among their father’s brothers, and you shall transfer the inheritance of their father to them.8Further, you shall speak to the sons of Israel, saying, ‘If a man dies and has no son, then you shall transfer his inheritance to his daughter.9If he has no daughter, then you shall give his inheritance to his brothers.10If he has no brothers, then you shall give his inheritance to his father’s brothers.11If his father has no brothers, then you shall give his inheritance to his nearest relative in his own family, and he shall possess it; and it shall be a statutory ordinance to the sons of Israel, just as the LORD commanded Moses.’”), is an homage to their faith. Here, in Numbers 36, it is about guarding the original inheritance part in the hands of the tribe to which it is given. The glory of God requires the avoidance of confusion about what He has given to His people.
