Leviticus 9:7

7. Make an atonement for thyself After seven days of consecration τελειωσις making perfect Leviticus 8:11, note,) Aaron is not absolutely holy and perfect, but only an imperfect shadow of the High Priest “who is holy, harmless, undefiled, and made higher than the heavens.” “Only as one who had been himself atoned for could the high priest make atonement for others, on the received principle, An innocent man must come and make an atonement for the guilty; but the guilty may not come and make an atonement for the innocent.” Delitzsch, Heb, 5:3. The person of the atoner must not be offensive to the Supreme Executor of the law. The high priest accompanied his sin offering with a threefold confession the first for himself and his own family, the second for the priesthood in general, and the third for all Israel. The first was thus: “O Jehovah, do thou expiate the misdeeds, the crimes, and the sins wherewith I have done evil, and have sinned before thee, I and my house, as it is written in the law of Moses thy servant.” “On that day shall the priest make an atonement for you, to cleanse you; that ye may be clean from all your sins before Jehovah.” Leviticus 16:30. For the nature of the Old Testament atonement see Leviticus 1:4; Leviticus 4:20, notes.
