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 lay them up in the tabernacle of the congregation,.... In the most holy place:

before the testimony; that is, the ark in which the testimony or the law was; here they were laid as in the presence of God, who was in a miraculous way to decide the controversy by them, and put an end to it; for upon the ark was the mercy seat, over which were the cherubim, the seat of the divine Majesty, and where none could come at them, and where no fraud could be supposed to be committed:

where I will meet with you; not with the people in person, who might not go at any time into the most holy place; nor with Aaron, who only might go into it on the day of atonement; but with Moses, the chief ruler and representative of the whole body of the people, and who might go in there at any time, to consult with God about matters of moment and difficulty, and where the Lord had said he would meet him, Exo 25:22; and now would, in a miraculous way, clearly show him, and the people of Israel by him, who was the priest he had chosen of all the tribes.
