15 This becomes even more evident when another priest arises in the likeness of Melchiz'edek, 16 who has become a priest, not according to a legal requirement concerning bodily descent but by the power of an indestructible life. 17 For it is witnessed of him, "Thou art a priest for ever, after the order of Melchiz'edek." 18 On the one hand, a former commandment is set aside because of its weakness and uselessness 19 (for the law made nothing perfect); on the other hand, a better hope is introduced, through which we draw near to God. 20 And it was not without an oath. 21 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.'" 22 This makes Jesus the surety of a better covenant. 23 The former priests were many in number, because they were prevented by death from continuing in office; 24 but he holds his priesthood permanently, because he continues for ever. 25 Consequently he is able for all time to save those who draw near to God through him, since he always lives to make intercession for them. 26 For it was fitting that we should have such a high priest, holy, blameless, unstained, separated from sinners, exalted above the heavens. 27 He has no need, like those high priests, to offer sacrifices daily, first for his own sins and then for those of the people; he did this once for all when he offered up himself. 28 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.

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.
