17:3 Aaron's name - Rather than Levi's, for that would have left the controversy undecided between Aaron and the other Levites, whereas this would justify the appropriation of the priesthood to Aaron's family. One rod - There shall be in this, as there is in all the other tribes, only one rod, and that for the head of their tribe, who is Aaron in this tribe: whereas it might have been expected that there should have been two rods, one for Aaron, and another for his competitors of the same tribe. But Aaron's name was sufficient to determine both the tribe, and that branch or family of the tribe, to whom this dignity should be affixed.
17:1-7 It is an instance of the grace of God, that, having wrought divers miracles to punish sin, he would work one more to prevent it. Twelve rods or staves were to be brought in. It is probable that they were the staves which the princes used as ensigns of their authority; old dry staves, that had no sap in them. They were to expect that the rod of the tribe, or prince, whom God chose to the priesthood, should bud and blossom. Moses did not object that the matter was sufficiently settled already; he did not undertake to determine it; but left the case before the Lord.
