(10) Thou shalt appoint.--Or, number. The word is the same as that which is used for the numbering of the Israelites generally (Numbers 1:19) and for the numbering of the Levites (Numbers 3:15).

Verse 10. - The stranger that cometh nigh. This constantly recurring formula has not always quite the same meaning: in Numbers 1:51 it signified any one not of the tribe of Levi; here it includes even the Levite who was not also a priest. The separation of the Levites for the ministry of the tabernacle was not to infringe in the least upon the exclusive rights of Aaron and his sons.

3:1-13 There was much work belonging to the priests' office, and there were now only Aaron and his two sons to do it; God appoints the Levites to attend them. Those whom God finds work for, he will find help for. The Levites were taken instead of the first-born. When He that made us, saves us, as the first-born of Israel were saved, we are laid under further obligations to serve him faithfully. God's right to us by redemption, confirms the right he has to us by creation.And thou shalt appoint Aaron and his sons,.... To the priestly office; this was done before, but is renewed for the confirmation of it, and repeated to put them in mind of it, that they be careful to execute it, as follows:

and they shall wait on their priest's office, to do what was peculiar to it, both in the holy and in the most holy place, at the altar, and within, the vail, where the Levites had nothing to do; and this is observed that the priests might take notice, that by the gift of the Levites to them, they were not excused from doing any part of service which was proper to them as priests; for they were given them that they might more readily attend their office, and be wholly employed in it; just as, under the Gospel dispensation, deacons were appointed to take care of the secular affairs of the church, that the apostles might give up themselves to the word of God and prayer, Acts 6:2,

and the stranger that cometh nigh shall be put to death; that comes nigh to perform any part of the priest's office peculiar to him as to offer sacrifice, burn incense, &c. whether he be a common Israelite, or even a Levite, as Korah was; any that was not a priest was reckoned a stranger, and so to be put to death for intruding into the office, as the above mentioned person was: so Aben Ezra interprets it of anyone that came nigh to a priest, to be with him or join with him in the execution of his office, whether an Israelite or a Levite, he shall die: the Targum of Jonathan adds, by flaming fire before the Lord.
