Indeed, the law appoints men in their weakness as high priests, but the word of the oath, which came later than the law, appoints a Son who has been made perfect for ever.
if it is the anointed priest who sins, thus bringing guilt on the people, then let him offer for the sin which he has committed a young bull without blemish to the Lord for a sin offering.
For it was fitting that he, for whom and by whom all things exist, in bringing many sons to glory, should make the pioneer of their salvation perfect through suffering.
Therefore he had to be made like his brethren in every respect, so that he might become a merciful and faithful high priest in the service of God, to make expiation for the sins of the people.
So also Christ did not exalt himself to be made a high priest, but was appointed by him who said to him, “Thou art my Son, today I have begotten thee”;
Those who formerly became priests took their office without an oath, but this one was addressed with an oath, “The Lord has sworn and will not change his mind, ‘Thou art a priest for ever.’ ”
He is without father or mother or genealogy, and has neither beginning of days nor end of life, but resembling the Son of God he continues a priest for ever.
