The Book of Deuteronomy is the fifth book of the Bible and the last of the Pentateuch or Torah, the five books written by Moses. Deuteronomy contains three sermons given by Moses to the Israelites who are to enter the promised land. The word Deuteronomy means 'second law giving' as the book reiterates the laws God has given to His people for the generation of Israelites who were not present when the laws were first given.
"on this side Jordan, in the land of Moab, began Moses to declare this law, saying, The Lord our God spake unto us in Horeb, saying, Ye have dwelt long enough in this mount."
In this first speech Moses recounts the adventures of the Israelites since they left Mount Sinai almost 40 years before, up until they came to Moab
