John Calvin's Bible Commentary
Numbers 33:8
8.And they departed from before Pi-hahiroth. He relates how the people marched forwards for three days; not so much in praise of their endurance, as in celebration of God’s wonderful power, who sustained so great a multitude without water. For we must bear in mind, what I have elsewhere shewn, that from the passage of the Red Sea to Marah there was no water found; whence the impiety of the people was the more detestable, since they there burst forth into rebellion on account of the bitter taste of the water. On the other side, the incomparable mercy of God shone forth, in that He condescended to refresh these churlish and provoking men in a pleasant and delightful station; for from their first encampment they were led on to Elim, where they found twelve fountains and seventy palm-trees. Moses passes briefly over the wilderness of Sin, as if nothing worthy of being recorded had occurred there; whereas the vile impiety of the people there betrayed itself, and the place was ennobled by a signal miracle, since the manna rained from heaven for the nourishment of the people, so that, the windows of heaven being opened, mortal man “did eat angels’ food.” He also briefly adverts to the want of water to drink at Rephidim: but he deemed it sufficient here to enumerate the stations, which might recall the various occurrences to the memory of the people. On the Graves of Concupiscence a memorial of God’s punishment was inscribed; but since he simply gives a list of other places, without any record of events, we may gather, as I have above stated, that he had no other design than to set before the eyes of the people the peregrination in which they had been engaged for forty years. He, however, cursorily mentions the death of Aaron; because his life had been prolonged, by God’s special blessing, for the good of the people, until the time approached when they were about to enter the promised land; since his authority was a useful and necessary restraint upon the ungovernable character of this headstrong people. At the same time the punishment inflicted upon the holy man should have reminded posterity that it was not without reason that their fathers had been so severely chastised, since they had not ceased to add sin to sin, when God had not spared even His own servant on account of a single transgression.
When he adds just afterwards, that the Canaanite then first heard of the coming the children of Israel, he indicates that God had put a veil over the eyes of their enemies, lest they should oppose them at an earlier period. For God so mitigated the severity of His judgment, that the exile of the Israelites was, at any rate, undisturbed, and free from outward molestation, as long as they had to wander in the desert.
