For every high priest is ordained to offer gifts and sacrifices: wherefore it is of necessity that this man have somewhat also to offer. Every high priest is ordained - Καθισταται, Is set apart, for this especial work.
Gifts and sacrifices - Δωρα τε και θυσιας· Eucharistic offerings, and sacrifices for sin. By the former, God's government of the universe, and his benevolence to his creatures in providing for their support, were acknowledged. By the latter, the destructive and ruinous nature of sin, and the necessity of an atonement, were confessed.
Wherefore - of necessity - If Christ be a high priest, and it be essential to the office of a high priest to offer atoning sacrifices to God, Jesus must offer such. Now it is manifest that, as he is the public minister, officiating in the true tabernacle as high priest, he must make an atonement; and his being at the right hand of the throne shows that he has offered, and continues to offer, such an atonement.
