The Book of Deut was the last book of the Five Books of Moses. It recorded three long speeches that Moses gave to the people of Israel before he died. It was set on the threshold of the promised land after the people of Israel wandered in the wilderness for 40 years. In the Book of Deuterogies, Moses re-announced God's law to the people of Israel and reminded them to obey God's commandments and laws before entering the land of Canaan. The purpose of the book was to exhort the second generation of Israel not to forget God's law before entering Canaan, so that they could become holy chosen people. The book emphasized the importance of loyalty to the covenant and warned people that breaking God's laws would bring disaster. The author of the book was Moses. Although some parts may have been added later, it was still considered a work of Moses 'time.
