Hebrews 5:3

And by reason thereof is bound, as for the people, so also for himself, to offer for sins.

Here the author touches on one of the great differences between the high priest of Israel and the Lord Jesus Christ; whereas they were, through infirmity and sins, required to offer blood for themselves, Christ, being sinless and undefiled, was laid under no such necessity. Milligan pointed out that this acknowledgment of guilt by the Aaronic priests was not confined to such a special occasion as the day of atonement, but was all-pervasive.

The high priest was required to offer sacrifices for his own sins, as well as for the sins of the people. This he did not only on special occasions and for special offenses (Leviticus 4:3-12), but also in all the regular daily, weekly, monthly, and yearly sacrifices that were offered for the sins of the nation; in all these there was an acknowledgment of his own guilt, as well as the guilt of the brethren.[3]

Although there can be no analogy between the high priesthood of Israel and the office of Christian ministers and teachers, there certainly is, however, the same common bond of the need of forgiveness that unites every teacher of God's word with the people who hear him. Every minister of the truth stands squarely in need of the forgiveness he preaches for others, both the teacher and the taught requiring the same remedy in the blood of Christ and the same loving obedience that it might become their final possession.
