What Is the Book of Deuteronomy About in the Bible? The Book of Deuteronomy is the fifth book of the Bible and the final book of the Torah or Pentateuch. Its name means “second law,” derived from the Greek “Deuteronomion.” This name reflects the book’s nature, as it recapitulates and expands upon the laws given to the Israelites earlier in the Pentateuch. Deuteronomy is a series of speeches by Moses, delivered to the Israelites on the plains of Moab, as they prepare to enter the Promised Land. These speeches emphasize the covenant between God and Israel, and they reiterate the laws and commandments that the Israelites are to follow in the land they are about to possess. https://www.freebiblestudyhub.com/archives/10276
