17 For he testifieth, Thou art a priest for ever after the order of Melchisedec. 18 For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof. 19 For the law made nothing perfect, but the bringing in of a better hope did; by the which we draw nigh unto God. 20 And inasmuch as not without an oath he was made priest: 21 (For those priests were made without [1] an oath; but this with an oath by him that said unto him, The Lord sware and will not repent, Thou art a priest for ever after the order of Melchisedec:)
17 For it is declared: "You are a priest forever, in the order of Melchizedek."
17 For it is witnessed of him, "You are a priest forever, after the order of Melchizedek." 18 For on the one hand, a former commandment is set aside because of its weakness and uselessness 19 (for the law made nothing perfect); but on the other hand, a better hope is introduced, through which we draw near to God. 20 And it was not without an oath. For those who formerly became priests were made such without an oath, 21 but this one was made a priest with an oath by the one who said to him: "The Lord has sworn and will not change his mind, 'You are a priest forever.'"
17 "priest forever in the royal order of Melchizedek." 18 The former way of doing things, a system of commandments that never worked out the way it was supposed to, was set aside; 19 the law brought nothing to maturity. Another way - Jesus! - a way that does work, that brings us right into the presence of God, is put in its place. 20 The old priesthood of Aaron perpetuated itself automatically, father to son, without explicit confirmation by God. 21 But then God intervened and called this new, permanent priesthood into being with an added promise: God gave his word; he won't take it back: "You're the permanent priest."
17 For He testifies: "You are a priest forever According to the order of Melchizedek." 18 For on the one hand there is an annulling of the former commandment because of its weakness and unprofitableness, 19 for the law made nothing perfect; on the other hand, there is the bringing in of a better hope, through which we draw near to God. 20 And inasmuch as He was not made priest without an oath 21 (for they have become priests without an oath, but He with an oath by Him who said to Him: "The Lord has sworn And will not relent, 'You are a priest forever According to the order of Melchizedek' "),
17 And the psalmist pointed this out when he prophesied, "You are a priest forever in the order of Melchizedek." 18 Yes, the old requirement about the priesthood was set aside because it was weak and useless. 19 For the law never made anything perfect. But now we have confidence in a better hope, through which we draw near to God. 20 This new system was established with a solemn oath. Aaron's descendants became priests without such an oath, 21 but there was an oath regarding Jesus. For God said to him, "The Lord has taken an oath and will not break his vow: 'You are a priest forever.'"
Matthew Henry's Commentary on Hebrews 7:17-21
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.
