John Durham opens his Exodus commentary with the sentence: "The Book of Exodus is the first book of the Bible". This is obviously meant to be a provocative statement that tries to lay more emphasis on the significance of the book of Exodus itself than on its placement after the book of Genesis. Indeed, it is striking that the exodus story introduced in the book of Exodus takes up four of the five books of the Pentateuch and that its foremost hero, Moses, even provides the name for the overall narrative in later Jewish and Christian tradition as the "Torah of Moses" or the "Five Books of Moses", even though these titles also includes the book of Genesis. The book of Exodus apparently also includes literary elements. Within the book of Exodus, the Priestly texts are especially prominent and extensive in the second half of the book.
