Two important distinctions are made in the case of the high priest, thus confirming his typical relation to Christ the anti-type:
(1) Aaron is anointed before the sacrifices are slain, while in the case of the priests the application of blood precedes the anointing. Christ the sinless One required no preparation for receiving the anointing oil, symbol of the Holy Spirit;
(2) upon the high priest only was the anointing oil poured. "God giveth not the Spirit by measure unto him" John 3:34 . "Thy God hath anointed Thee with the oil of gladness above Thy fellows." Hebrews 1:9 .
8:34 As he hath done this day, so the LORD hath commanded to do, to make an atonement for you.
