One of the great puzzles of the story of the Exodus is that the Israelites believed they would die of hunger because they had no food (Exodus 16:3), yet they had rich herds of cattle. This can best be explained by the scholarly view that the Book of Exodus was not written until many centuries after the time attributed to the Exodus. When writing of the hardships of the Israelites, the author simply did not check back to the point in the story where it was explained that the Israelites took their cattle with them.

The book that recounts how God cared for the Israelites is the Bible, specifically the Old Testament books of Exodus, Leviticus, Numbers, and Deuteronomy. These books describe God's provision and protection for the Israelites during their exodus from Egypt and journey to the Promised Land.
