The Book of Deutoronomy is the fifth book of the Old Testament, with Moses as its author. The book is a collection of Moses’ sermons to the Israelites shortly before their arrival at the Promised Land.
In this book, Moses repeatedly reminds the Israelites about the sins that had prevented their ancestors from entering the Promised Land, as well as to obey God. He also reminds the people of the events that happened during the 40 years of wilderness wanderings which have brought them to this moment. It is also a book of law as it goes into details about the moral laws, as well as Moses’ life and briefly his death.
