23 Now there have been many of those priests, since death prevented them from continuing in office; 24 but because Jesus lives forever, he has a permanent priesthood. 25 Therefore he is able to save completely[1] those who come to God through him, because he always lives to intercede for them. 26 Such a high priest truly meets our need-one who is holy, blameless, pure, set apart from sinners, exalted above the heavens. 27 Unlike the other high priests, he does not need to offer sacrifices day after day, first for his own sins, and then for the sins of the people. He sacrificed for their sins once for all when he offered himself. 28 For the law appoints as high priests men in all their weakness; but the oath, which came after the law, appointed the Son, who has been made perfect forever.

Matthew Henry's Commentary on Hebrews 7:23-28

Commentary on Hebrews 7:11-25

(Read Hebrews 7:11-25)

The priesthood and law by which perfection could not come, are done away; a Priest is risen, and a dispensation now set up, by which true believers may be made perfect. That there is such a change is plain. The law which made the Levitical priesthood, showed that the priests were frail, dying creatures, not able to save their own lives, much less could they save the souls of those who came to them. But the High Priest of our profession holds his office by the power of endless life in himself; not only to keep himself alive, but to give spiritual and eternal life to all who rely upon his sacrifice and intercession. The better covenant, of which Jesus was the Surety, is not here contrasted with the covenant of works, by which every transgressor is shut up under the curse. It is distinguished from the Sinai covenant with Israel, and the legal dispensation under which the church so long remained. The better covenant brought the church and every believer into clearer light, more perfect liberty, and more abundant privileges. In the order of Aaron there was a multitude of priests, of high priests one after another; but in the priesthood of Christ there is only one and the same. This is the believer's safety and happiness, that this everlasting High Priest is able to save to the uttermost, in all times, in all cases. Surely then it becomes us to desire a spirituality and holiness, as much beyond those of the Old Testament believers, as our advantages exceed theirs.

Commentary on Hebrews 7:26-28

(Read Hebrews 7:26-28)

Observe the description of the personal holiness of Christ. He is free from all habits or principles of sin, not having the least disposition to it in his nature. No sin dwells in him, not the least sinful inclination, though such dwells in the best of Christians. He is harmless, free from all actual transgression; he did no violence, nor was there any deceit in his mouth. He is undefiled. It is hard to keep ourselves pure, so as not to partake the guilt of other men's sins. But none need be dismayed who come to God in the name of his beloved Son. Let them be assured that he will deliver them in the time of trial and suffering, in the time of prosperity, in the hour of death, and in the day of judgment.
