Here we have, I. Orders given for the bringing in of a rod for every tribe (which was peculiarly significant, for the word here used for a rod sometimes signifies a tribe, as particularly Num 34:13), that God by a miracle, wrought on purpose, might make it known on whom he had conferred the honour of the priesthood. 1. It seems then the priesthood was a preferment worth seeking and striving for, even by the princes of the tribes. It is an honour to the greatest of men to be employed in the service of God. Yet perhaps these contended for it rather for the sake of the profit and power that attended the office than for the sake of that in it which was divine and sacred. 2. It seems likewise, after all that had been done to settle this matter, there were those who would be ready upon any occasion to contest it. They would not acquiesce in the divine appointment, but would make an interest in opposition to it. They strive with God for the dominion; and the question is whose will shall stand. God will rule, but Israel will not be ruled; and this is the quarrel. 3. It is an instance of the grace of God that, having wrought divers miracles to punish sin, he would work one more on purpose to prevent it. God has effectually provided that the obstinate shall be left inexcusable, and every mouth shall be stopped. Israel were very prone to murmur both against God and against their governors. "Now," said God, "I will make to cease from me the murmurings of the children of Israel, Num 17:5. If any thing will convince them, they shall be convinced; and, if this will not convince them, nothing will." This was to be to them, as Christ said the sign of the prophet Jonas (that is, his own resurrection) should be to the men of that generation, the highest proof of his mission that should be given them. The directions are, (1.) That twelve rods or staves should be brought in. It is probable that they were not now fresh cut out of a tree, for then the miracle would not have been so great; but that they were the staves which the princes ordinarily used as ensigns of their authority (of which we read Num 21:18), old dry staves, that had no sap in them, and it is probable that they were all made of the almond-tree. It should seem they were but twelve in all, with Aaron's, for, when Levi comes into the account, Ephraim and Manasseh make but one, under the name of Joseph. (2.) That the name of each prince should be written upon his rod, that every man might know his own, and to prevent contests. Writing is often a good preservative against strife, for what is written may be appealed to. (3.) That they should be laid up in the tabernacle, for one night, before the testimony, that is, before the ark, which, with its mercy seat, was a symbol, token, or testimony, of God's presence with them. (4.) They were to expect, being told it before, that the rod of the tribe, or prince, whom God chose to the priesthood, should bud and blossom, Num 17:5. It was requisite that they should be told of it, that it might appear not to be casual, but according to the counsel and will of God.

II.The preparing of the rods accordingly. The princes brought them in, some of them perhaps fondly expecting that the choice would fall upon them, and all of them thinking it honour enough to be competitors with Aaron, and to stand candidates, even for the priesthood (Num 17:7); and Moses laid them up before the Lord. He did not object that the matter was sufficiently settled already, and enough done to convince those that were not invincibly hardened in their prejudices. He did not undertake to determine the controversy himself, though it might easily have been done; nor did he suggest that it would be to no purpose to offer satisfaction to a people that were willingly blind. But, since God will have it so, he did his part, and lodged the case before the Lord, to whom the appeal was made by consent, and left it with him.

And thou shalt write Aaron's name upon the rod of Levi,.... Or upon the rod that was for the tribe of Levi; the name of "Aaron" was to be written, not the word "Levi", or a "Levite", as Josephus (e); for that would not have decided the controversy about the priesthood, which chiefly lay between the Levites and the family of Aaron, who were of the same tribe:

for one rod shall be for the head of the house of their fathers; one rod for the head or prince of every tribe, every prince representing his own tribe he was the head of, and the rod the prince; and though the tribe of Levi was divided into two families, the family of the priests, and the family of the Levites; yet, as Jarchi observes, they were but one tribe, and so one rod for them, as for the other tribes.
