Leviticus 16:6 - Exposition

And Aaron shall offer his bullock … and make an atonement for himself, and for his house. The first step is an expiatory offering to reconcile the officiating priest and the remainder of the priestly house to God. This was necessary before his offerings for the people could be accepted. It indicates the defects inherent in a priest whose nature was only that of man, which is compassed about with infirmities. The offering here commanded is not the slaying, but the solemn presentation, of the bullock to the Lord. In after times the following form of confession was used by the high priest when he laid his hand upon the bullock:—"O Lord, I have committed iniquity; I have transgressed; I have sinned, I and my house. O Lord, I entreat thee, cover over the iniquities, the transgressions, and the sins which I have committed, transgressed, and sinned before thee, I and my house; even as it is written in the Law of Moses thy servant, 'For on that day will he cover over for you, to make you clean; from all your transgressions before the Lord ye shall be cleansed" (Edersheim, 'Temple Service').
