who is speaking in the book of deuteronomy
Book of Deuteronomy Chapters 1–30 of the book consist 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 recounts the forty years of wilderness wanderings which had led to that 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 to follow Yahweh and 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.[1] The final four chapters (31–34) contain the Song of Moses, the Blessing of Moses, and narratives recounting the passing of the mantle of leadership from Moses to Joshua and, finally, the death of Moses on Mount Nebo.
Old Testament Christians traditionally divide the Old Testament into four sections: (1) the first five books or Pentateuch (Torah); (2) the history books telling the history of the Israelites, from their conquest of Canaan to their defeat and exile in Babylon; (3) the poetic and "Wisdom books" dealing, in various forms, with questions of good and evil in the world; and (4) the books of the biblical prophets, warning of the consequences of turning away from God.
