In my Bible study we just got finished with the book of Exodus. I didn’t realize until reading the commentary on the last chapter that the book wraps up only one year after they left Egypt.
Another thing: When I was younger, I misunderstood all the references to “the tabernacle.” Being raised Catholic, I thought the tabernacle referred to a little cabinet.
However, in Exodus it refers to the tent which contained the Ark and other important items. (The word in both usages means “where God dwells” but they obviously refer to different physical structures.)
For those unfamiliar with the text, at night God would hover as a pillar of fire above the tabernacle, while during the day as a column of smoke. Thus the children of Israel would know He was literally in their midst, leading them out of slavery and to the Promised Land.
