Num 36:5-9
Moses declared that what they had affirmed was right (כּן), and then, by command of Jehovah, he told the daughters of Zelophehad that they might marry whoever pleased them (the suffix ־הם, attached to בּעיני, for ־הן, as in Exo 1:21; Gen 31:9, etc.), but that he must belong to the family of their father’s tribe, that is to say, must be a Manassite. For (Num 36:7) the inheritance was not to turn away the Israelites from one tribe to another (not to be transferred from one to another), but every Israelite was to keep to the inheritance of his father’s tribe, and no one was to enter upon the possession of another tribe by marrying an heiress belonging to that tribe. This is afterwards extended, in Num 36:8 and Num 36:9, into a general law for every heiress in Israel.
In Num 36:10-12 it is related that, in accordance with these instructions, the five daughters of Zelophehad, whose names are repeated from Num 26:33 and Num 27:1 (see also Jos 17:3), married husbands from the families of the Manassites, namely, sons of their cousins (? uncles), and thus their inheritance remained in their father’s tribe (על היה, to be and remain upon anything).
