(8, 9) And every daughter, that possesseth an inheritance . . . --The particular direction which was given in the case of the daughters of Zelophehad is extended in these verses into a general and permanent law that no heiress in Israel should marry out of her father's tribe, in order that the inheritance might not be transferred from one tribe to another, and thus, in process of time, the division of the land amongst the tribes, which was made under Divine direction, be materially changed.

36:5-12 Those who consult the oracles of God, concerning the making of their heavenly inheritance sure, shall not only be directed what to do, but their inquiries shall be graciously accepted. God would not have one tribe enriched at the expense of another. Each tribe was to keep to its own inheritance. The daughters of Zelophehad submitted to this appointment. How could they fail to marry well, when God himself directed them? Let the people of God learn how suitable and proper it is, like the daughters of Israel, to be united only to their own people. Ought not every true believer Israel, to be united only to their own people. Ought not every true believer in Jesus, to be very attentive in the near and tender relations of life, to be united only to such as are united to the Lord? All our intentions and inclinations ought to be subjected to the will of God, when that is made known to us, and especially in contracting marriage. Although the word of God allows affection and preference in this important relation, it does not sanction that foolish, ungovernable, and idolatrous passion, which cares not what may be the end; but in defiance of authority, determines upon self-gratification. All such conduct, however disguised, is against common sense, the interests of society, the happiness of the marriage relation, and, what is still more evil, against the religion of Christ.And every daughter that possesseth an inheritance in any tribe if the children of Israel,.... For the same law which gave the daughters of Zelophehad right to their father's inheritance, gave every other daughter in Israel a right to inherit where there were no sons, Numbers 27:8 and every such daughter, according to this law:

shall be wife unto one of the family of the tribe of her father; marry into her father's tribe and family; by which it appears that such who were not heiresses might marry persons of another family, and even of another tribe:

that the children of Israel may enjoy every man the inheritance of his fathers; of his father's brethren, or of those that are near akin to him.
