The Book of Deuteronomy is the fifth book of the Torah, where it is called Devarim, "the words", and the fifth book of the Christian Old Testament, where it is otherwise called the Fifth Book of Moses.
Sections 1 TO 30 of the book comprise of three lessons or discourses conveyed to the Israelites by Moses on the fields of Moab, quickly before they enter the Promised Land. The primary message describes the forty years of wild wanderings which had prompted that second, and finishes with an admonishment to notice the law. The subsequent lesson helps the Israelites to remember the need to observe Yahweh and the regulations he has given them, on which their ownership of the land depends. What's more, the third message offers the solace that, even should Israel demonstrate untrustworthy thus lose the land, with atonement all can be reestablished.
The last four sections 31 TO 34 contain the Song of Moses, the Blessing of Moses, and the stories describing the death of the mantle of administration from Moses to Joshua and, at last, the passing of Moses on Mount Nebo.
