| Geneva Study Bible {11} And they truly were many priests, because they were not suffered to continue by reason of death: (11) Another argument for the same purpose. The Levitical priests (as mortal men) could not be everlasting, but Christ, as he is everlasting, so has he also an everlasting priesthood, making most effectual intercession for them who come to God by him. People's New Testament 7:23 They truly were many priests. Since they were removed by death, there were in succession many Aaronic high priests. Wesley's Notes 7:23 They were many priests - One after another. Jamieson-Fausset-Brown Bible Commentary 23. Another proof of superiority; the Levitical priests were many, as death caused the need of continually new ones being appointed in succession. Christ dies not, and so hath a priesthood which passes not from one to another. were-Greek, "are made." many-one after another; opposed to His "unchangeable (that does not pass from one to another) priesthood" (Heb 7:24). not suffered to continue-Greek, "hindered from permanently continuing," namely, in the priesthood. Matthew Henry's Concise Commentary 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. |
