What is the significance of Deuteronomy?

Deuteronomy contains a restatement of the Torah, or Law, addressed to the 'new generation' who had arisen over the 40 years in the wilderness. The name itself comes from the two Greek Words 'deutero' (second) and 'nomos' (Law). As such, the title means 'second Law'. Moses is essentially giving his parting address to the nation before his own death and more importantly before the nation was to enter the promised land. This entry, and the future of the nation is often referred to in the book. In particular Moses is concerned about the future idolatry, and resultant judgment, which he foresaw, and against which he sternly warned the people.
