Something interesting I came across while learning the Ramban on the parsha:
“And Moses wrote their goings out according to their journeys by the commandment of the Lord "(ibid. ver. 2). It was indeed most necessary that these should be written. For miracles are only convincing to those who witnessed them; whilst coming generations, who know them only from the account given by others, may consider them as untrue.
But miracles cannot continue and last for all generations; it is even inconceivable [that they should be permanent]. Now the greatest of the miracles described in the Law is the stay of the Israelites in the wilderness for forty years, with a daily supply of manna. This wilderness, as described in Scripture, consisted of places "wherein were fiery serpents and scorpions, and drought, where there was no water" (Deut. viii. 15) ; places very remote from cultivated land, and naturally not adapted for the habitation of man, "It is no place of seed, or of figs, or of vines, or of pomegranates, neither is there any water to drink " (Num. xx. 5); "A land that no man passed through, and where no man dwelt" (Jer. ii. 6). [In reference to the stay of the Israelites in the wilderness], Scripture relates, “Ye have not eaten bread, neither have ye drunk wine or strong drink" (Deut. xix. 5). All these miracles were wonderful, public, and witnessed by the people. But God knew that in future people might doubt the correctness of the account of these miracles; in the same manner as they doubt the accuracy of other narratives ; they might think that the Israelites stayed in the wilderness in a place not far from inhabited land, where it was possible for man to live [in the ordinary way] ; that it was like those deserts in which Arabs live at present; or that they dwelt in such places in which they could plow, sow, and reap, or live on some vegetable that was growing there ; or that manna came always down in those places as an ordinary natural product ; or that there were wells of water in those places. In order to remove all these doubts and to firmly establish the accuracy of the account of these miracles, Scripture enumerates all the stations, so that coming generations may see them, and learn the greatness of the miracle which enabled human beings to live in those places forty years.
