The book consists of three sermons or speeches delivered to the Israelites by Moses on the plains of Moab, shortly before they enter the Promised Land. The first sermon recapitulates the forty years of wilderness wanderings which have led to this moment, and ends with an exhortation to observe the law (or teachings), later referred to as the Law of Moses; the second reminds the Israelites of the need for exclusive allegiance to one God and observance of the laws (or teachings) he has given them, on which their possession of the land depends; and the third offers the comfort that even should Israel prove unfaithful and so lose the land, with repentance all can be restored. 2]
