(Num 36:1-4) The inheritance of the daughters of Zelophehad.
(Num 36:5-12) The daughters of Zelophehad are to marry in their own tribe.
(Num 36:13) Conclusion.
The heads of the tribe of Manasseh represent the evil which might follow, if the daughters of Zelophehad should marry into any other tribes. They sought to preserve the Divine appointment of inheritances, and that contests and quarrels should not rise among those who should come afterwards. It is the wisdom and duty of those who have estates in the world, to settle them, and to dispose of them, so that no strife and contention may arise.
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.
These are the judgments the Lord commanded in the plains of Moab. Most of them related to the settlement in Canaan, into which the Israelites were now entering. Whatever new condition God, by his providence, brings us into, we must beg him to teach us the duties of it, and to enable us to do them, that we may do the work of the day in its day, the duty of a place in its place.
