John Calvin's Bible Commentary
Numbers 34:16
16And the Lord spake unto Moses. The question here arises, if the Israelites were to divide the land among themselves by lot, wherefore was the authority of the judges required, as if there was anything for them to decide? But if we consider what has been lately shown, that reference was to be had, in the distribution of the land, to the numbers in every tribe, it was requisite for two purposes, — first, that God might show by His decree the districts respectively assigned to them; and, secondly, that their dimensions might be proportionate to the number of their occupants. For the casting of lots was still necessary, because many would have been averse to the sea-coast, or would have preferred the center of the land to its extremities, or would have been unwilling to be banished to the mountains; in short, they would have contended with each other beyond measure in murmurings and strife. On this account the lots were cast, by the decision of which God placed the several tribes in whatever position He pleased, although the judges, together with the High Priest and Joshua, had before divided the land into ten portions. But after it was declared in what district the several tribes were to dwell, as if God had there designated their abodes, the determination of men was again necessarily had recourse to, as to how far, and in what direction, the boundaries of the greater tribes were to extend; otherwise the lesser tribes would have refused to be cooped up in a less convenient position. And although the supreme authority was justly vested in Eleazar and Joshua, lest God should expose them to calumny and ill-will, He associated with them a council, in which also there was a prudent precaution against rivalry, for each of the twelve tribes contributed its judge to preside over the distribution, so that none might complain of being aggrieved. Moreover, inasmuch as it was of great importance that the possession, once established, should be secured to posterity, first of all the names of the princes are recorded, in order to give certainty to the history; and, secondly, as had been stated at the beginning of the chapter, so also it is repeated at the end that they were chosen by God, from whence the Israelites learnt that the boundaries then fixed could not be altered without overthrowing the authority of God Himself.
