Why does Deuteronomy repeat the law?

This might seem redundant to us, but we need to remember that most of the original audience had never heard the law given from Moses, because 40 years had transpired since the giving of the law. This would have been an important refresher for the people. Norman Geisler writes, “This book was written to the new generation, those under twenty years of age when they came out of Egypt. This second giving of the law was a renewal of the covenant that God had made with their fathers. This new generation received God’s charge to inherit their promised blessings.”[1] Likewise, Gleason Archer writes that Homer’s Odyssey “gives a summary restatement of the action of the Iliad in direct discourse, as told by famous participants in the Trojan War.”[2]
