Numbers 33:2
And Moses wrote their goings out according to their journeys by the commandment of the LORD: and these are their journeys according to their goings out. And Moses wrote their goings out according to their journeys by the commandment of the LORD: and these are their journeys according to their goings out.
Moses himself wrote the account of Israel's goings out, journeys, stages, encampments, and places of departure by the commandment of the Lord, and this supports Mosaic authorship of this material. The journeys he recorded span the forty years in the wilderness on the way from Egypt toward Canaan, including the region around Mount Sinai. The chapter preserves the names of the journeys and encampments, including eighteen encampments between Hazeroth and Kadesh-barnea where little is recorded of what happened and for most places only the names remain. The list that begins here contains many hard-to-pronounce names, yet it also contains refreshing oases such as the fountains and palm trees of Elim.
In its setting among chapters 31 to 33, the passage teaches that no secret sin can be hidden from God. To claim Moses never wrote any of the Bible and that the books credited to him were imagined for fraud denies what the verse states and denies divine inspiration. To limit inspiration to guidance into truth and preservation from error only in religion, faith, and morals, while still charging error in religion and morals and calling the Bible's errors innumerable and its untrustworthiness unlimited, discards even that limited inspiration. Since the Bible's authority comes from its inspiration and trustworthiness, stripping them away leaves it shorn of power and comfort and leaves its readers in darkness and despair.
