Numbers 13:2

2.Of every tribe of their fathers shall ye send a man. If all had been taken from one tribe, or from any single portion of the people, their fidelity might have been suspected by the others. God, therefore, would have each tribe assured by its own witness, in order that their report might be more unquestionable. All cause for jealousy was also to be taken away; lest, if any tribe had been passed over, it might have excepted against the messengers, whom it supposed to have been elected in contempt of it. This, then, was the advantage of the equal distribution, lest any sinister suspicion or offence might disturb the unanimity of the whole people. Secondly, it is required that they should be possessed of personal dignity, since God commands that chief men should be chosen, whose testimony would be of greater authority; for it would have been easy to throw discredit upon obscure individuals. Since, however, both precautions were unsuccessful, it appears from hence that there is no counsel so wise and salutary as not to be capable of perversion by the wickedness of mankind. Thus this excellent providence of God rendered the people the more inexcusable. At the same time, God has reminded us once for all by this example that, however those, who seemed to be like pillars, may totter and stumble, or even fall altogether, still our minds must be supported by faith, so as not to give way.

Their names are enumerated, in perpetual remembrance of their ignominy, except in the case of two, Joshua and Caleb; for it was just that their crime should be handed down to all ages, and that the infamy of their perfidiousness should never be blotted out, since they endeavored, as far as in them lay, to bring to naught the promise and the grace of God.

Moses gave the name of Jehoshua to the son of Nun in the spirit of prophecy, as a presage of the exalted function to which he was destined. Ambition is so rash, that men are often disappointed in the result, when they invent titles of honor of their own accord; but Moses was not induced by the blindness of affection to change the name Oshea into Jehoshua; but God directed his tongue and mind thus to commend, beforehand, him who (49) was to be the future minister of their preservation. Still it cannot be inferred with certainty from this passage at what time the new name was given him; for it is not specified that he was called Jehoshua at the time he was sent out; nay, it is probable that he had been previously thus distinguished, viz., from the period in which he had been associated with Moses as his companion and minister in all important matters.

Calvin here alludes to the apparent contradiction arising from the fact that Joshua had already been called by his new name in Exodus 17:9; and Numbers 11:28, which, as Hengstenberg remarks, was a topic of discussion as early as the times of Justin Martyr. Hengstenberg reviews the three modes of meeting the difficulty proposed, viz., 1. That he was so called in the earlier passages by prolepsis. 2. That Moses now only renewed the name. 3. That a statement is here made of what had taken place a considerable time before. To this view he himself inclines, and says, “That the author here first mentioned that he, whom he had originally called simply Joshua, originally bore the name of Hoshea, was not without good reason. What had been hitherto related of Joshua, belonged to him as a servant of God; the sacred name was, therefore, properly employed. But here Hoshea must stand; for he went to spy out the land, not as a servant of Moses, but as one of the heads of the children of’ Israel,’ — one of the plenipotentiaries of the congregation.” — Genuineness of Pentateuch, vol. 2, p. 323.
