Although in every point of view, politically and nationally considered, this law seems good, yet certainly it had a much higher significance, in the prospect of gospel mercies. JESUS is the Head of the tribe of his people. With him must all alliance be made, and with his people in him. The spiritual law of the gospel is now to this purpose: let the people marry to whom they think best; only to the family of the tribe of JESUS. Or, as the apostle says, be ye not unequally yoked with unbelievers. 2 Corinthians 6:14-18.
Numbers 36:5-13
5 And Moses commanded the children of Israel according to the word of the LORD, saying, The tribe of the sons of Joseph hath said well.
6 This is the thing which the LORD doth command concerning the daughters of Zelophehad, saying, Let them marrya to whom they think best; only to the family of the tribe of their father shall they marry.
7 So shall not the inheritance of the children of Israel remove from tribe to tribe: for every one of the children of Israel shall keepb himself to the inheritance of the tribe of his fathers.
8 And every daughter, that possesseth an inheritance in any tribe of the children of Israel, shall be wife unto one of the family of the tribe of her father, that the children of Israel may enjoy every man the inheritance of his fathers.
9 Neither shall the inheritance remove from one tribe to another tribe; but every one of the tribes of the children of Israel shall keep himself to his own inheritance.
10 Even as the LORD commanded Moses, so did the daughters of Zelophehad:
11 For Mahlah, Tirzah, and Hoglah, and Milcah, and Noah, the daughters of Zelophehad, were married unto their father's brothers' sons:
12 And they were married into the families of the sons of Manasseh the son of Joseph, and their inheritance remained in the tribe of the family of their father.
13 These are the commandments and the judgments, which the LORD commanded by the hand of Moses unto the children of Israel in the plains of Moab by Jordan near Jericho.
