And Joshua the son of Nun, the servant of Moses. It is obvious that this foolish and preposterous jealousy arose from a good source. Joshua saw that Moses was so preeminent above all others, as to be justly deemed, after God, the head of the people; he feared, therefore, lest, if any portion of his superiority should be withdrawn, the grace of God would be dispelled and lost. We know, too, that almost every change is injurious, and apt to give a shock to public affairs. In asserting, then, the rights of Moses, he desired, as far as he could, to consult the welfare of all; but the excess of his zeal had some alloy in it, in consequence of the immoderate affection and love which he bore to Moses; just as it often happens to ourselves, that although our desires have a right object, they still go astray into erroneous feelings. So, then, let us learn to revere the most illustrious servants of Christ, as that God alone should be supreme; and that He, who is far above all, should still maintain His pre-eminence. And this will be the case, if we hold fast to the principle, that although "there are diversities of gifts," yet there is but one Spirit from whom they flow; and although there are "differences of administrations," yet but one Lord who must be served, (1-Corinthians 12:4, 5;) which also Paul confirms elsewhere, where he teaches us that the gifts are so distributed as that no individual should have all, but each "according to the measure of the gift of Christ." (Ephesians 4:7.)

My lord Moses, forbid them -
How often have I blindly done
What zealous Joshua did,
Impatient to the rulers run,
And cried, "My lords, forbid!
Silence the schismatics, constrain
Their thoughts with ours t' agree,
And sacrifice the souls of men
To idol unity!"

And Joshua the son of Nun, the servant of Moses, [one] of his (q) young men, answered and said, My lord Moses, (r) forbid them.
(q) Or, a young man whom he had chosen from his youth.
(r) Such blind zeal was in the apostles, (Mark 9:38; Luke 9:44).

And Joshua the son of Nun, the servant of Moses,.... That waited upon him, and ministered to him, and executed his orders, especially in civil things, and was to be his successor:
one of his young men; not that Joshua was a young man in age, for he must be now between fifty and sixty years of age; see Gill on Exodus 33:11; nor does the word necessarily suppose that those men were young among whom Joshua was; but choice excellent persons, the principal servants of Moses, at the head of whom Joshua was being his prime minister: the Targum of Onkelos and the Syriac version render it, "from his youth", joining it with the word servant, as if he was the servant of Moses from his youth, or ever since he was a young man; but Moses had not been out of Midian but about two years, where he had kept his father's sheep; however, he
answered and said, my lord Moses, forbid them; prophesying, restrain them from it, suffer them not to go on in it; he would have him exert his authority as the chief magistrate, which he thought was affected by their prophesying without his knowledge and consent; and because a word from the root here used signifies a prison, some here interpret it,"put them in prison,''which is a sense Jarchi mentions; but it can hardly be thought that Joshua meant that such rigorous measures should be taken, only that they should be rebuked for what they had done, and be charged for the future to be silent.

One of his young men - Or, one of his choice ministers, which may be emphatically added, to note that even great and good men may mistake about the works of God. Forbid them - He feared either schism, or sedition, or that by their usurpation of authority, independently upon Moses, his power and esteem might be lessened.
