Leviticus 8:7 describes Aaron being clothed in the sacred garments of the high priest. At Aaron's death those same vestments were removed from him by Moses and put upon Eleazar, marking Eleazar's divinely appointed succession to the office. Because of Aaron's sin at Kadesh he would not continue to serve as high priest in Canaan.
