Deuteronomy 34:5-8

34:5 So Moses, the servant of the Lord, died there in the land of Moab as the Lord had said. 34:6 He buried him in the land of Moab near Beth Peor, but no one knows his exact burial place to this very day. 34:7 Moses was 120 years old when he died, but his eye was not dull nor had his vitality departed. 34:8 The Israelites mourned for Moses in the deserts of Moab for thirty days; then the days of mourning for Moses ended.
