Under God's instruction, Moses kept a log of every time they moved, camp by camp.
In today's passage, Moses added the list of all the stops to the biblical record.
And Moses did a lot of writing. Earlier he commanded tribal leaders to list the names of all the men of fighting age. He had made a written record of the first three books of the Bible (Genesis, Exodus, Leviticus). At some point he recorded Numbers and Deuteronomy as well.
With papyrus running at most 25 inches per sheet, that's a lot of papyrus.
When the Egyptians sent them off with gifts of gold and silver, did they include papyrus in the gift bags?
Moses had a royal education. But I've always been amazed at the range of skills exhibited by a people who spent their days making stones for the pyramids. Musicians and artists, weavers and artists, goldsmiths and clerks.
Details matter to God. Names, places, times. If He wanted Moses to keep a record, I bet He expects us to account for our time as well.
