‏ Hebrews 7:18-24

Verse 18

For there is verily a disannulling - There is a total abrogation, προαγουσης εντολης, of the former law, relative to the Levitical priesthood. See Heb 7:19.

For the weakness - It had no energy; it communicated none; it had no Spirit to minister; it required perfect obedience, but furnished no assistance to those who were under it.

And unprofitableness - No man was benefited by the mere observance of its precepts: it pardoned no sin, changed no heart, reformed no life; it found men dead in trespasses and sins, and it consigned them to eternal death. It was therefore weak in itself, and unprofitable to men.

The Jews, who still cleave to it, are a proof that it is both weak and unprofitable; for there is not a more miserable, distressed, and profligate class of men on the face of the earth.
Verse 19

For the law made nothing perfect - It completed nothing; it was only the outline of a great plan, the shadow of a glorious substance; see on Heb 7:11 (note). It neither pardoned sin, nor purified the heart, nor gave strength to obey the moral precepts. Ουδεν, nothing, is put here for ουδενα, no person.

But the bringing in of a better hope - The original is very emphatic, επεισαγωγη, the superintroduction, or the after introduction; and this seems to be put in opposition to the προαγουσα εντολη, the preceding commandment, or former Levitical law, of Heb 7:18. This went before to prepare the way of the Lord; to show the exceeding sinfulness of sin, and the strict justice of God. The better hope, which referred not to earthly but to spiritual good, not to temporal but eternal felicity, founded on the priesthood and atonement of Christ, was afterwards introduced for the purpose of doing what the law could not do, and giving privileges and advantages which the law would not afford. One of these privileges immediately follows: -

By the which we draw nigh unto God - This is a sacerdotal phrase: the high priest alone could approach to the Divine presence in the holy of holies; but not without the blood of the sacrifice, and that only once in the year. But through Christ, as our high priest, all believers in him have an entrance to the holiest by his blood; and through him perform acceptable service to God. The better hope means, in this place, Jesus Christ, who is the author and object of the hope of eternal life, which all his genuine followers possess. He is called our hope, 1Tim 1:1; Col 1:27.
Verse 20

Not without an oath - "The apostle's reasoning here is founded on this, that God never interposed his oath, except to show the certainty and immutability of the thing sworn. Thus he sware to Abraham, Gen 22:16-18, that in his seed all the nations of the earth should be blessed; and to the rebellious Israelites, Deu 1:34, Deu 1:35, that they should not enter into his rest; and to Moses, Deu 4:21, that he should not go into Canaan; and to David, Psa 89:4, that his seed should endure for ever, and his throne unto all generations. Wherefore, since Christ was made a priest, not without an oath that he should be a priest for ever, after the similitude of Melchisedec, that circumstance showed God's immutable resolution never to change or abolish his priesthood, nor to change or abolish the covenant which was established on his priesthood; whereas the Levitical priesthood and the law of Moses, being established without an oath, were thereby declared to be changeable at God's pleasure." This judicious note is from Dr. Macknight.
Verse 21

Those priests - The Levitical, were made without an oath, to show that the whole system was changeable, and might be abolished.

But this - The everlasting priesthood of Christ, with an oath, to show that the Gospel dispensation should never change, and never be abolished.

By him - God the Father, that said unto him - the promised Messiah, Psa 110:4, The Lord sware, to show the immutability of his counsel, and will not repent - can never change his mind nor purpose, Thou art a priest for ever - as long as time shall run, and the generations of men be continued on earth. Till the necessity of the mediatorial kingdom be superseded by the fixed state of eternity, till this kingdom be delivered up unto the Father, and God shall be all in all, shall this priesthood of Christ endure.
Verse 22

By so much - This solemn, unchangeable oath of God, was Jesus made a surety, εγγυος, a mediator, one who brings the two parties together, witnesses the contract, and offers the covenant sacrifice on the occasion. See at the end of the chapter.

A better testament - Κρειττονος διατηκης· A better covenant; called, in the title to the sacred books which contain the whole Christian code, Ἡ Καινη Διαθηκη, The New Covenant, thus contradistinguished from the Mosaic, which was the old covenant; and this is called the new and better covenant, because God has in it promised other blessings, to other people, on other conditions, than the old covenant did. The new covenant is better than the old in the following particulars:

1. God promised to the Jewish nation certain secular blessings, peculiar to that nation, on condition of their keeping the law of Moses; but under the new covenant he promises pardon of sin, and final salvation to all mankind, on condition of believing on Jesus Christ, and walking in his testimonies.

2. The Jewish priests, fallible, dying men, were mediators of the old covenant, by means of their sacrifices, which could not take away sin, nor render the comers thereunto perfect. But Jesus Christ, who liveth for ever, who is infinite in wisdom and power, by the sacrifice of himself has established this new covenant, and by the shedding of his blood has opened the kingdom of heaven to all believers.
Verse 23

And they truly were many priests - Under the Mosaic law it was necessary there should be a succession of priests, because, being mortal, they were not suffered to continue always by reason of death.
Verse 24

But this - Ὁ δε, But he, that is, Christ, because he continueth ever - is eternal, hath an unchangeable priesthood, απαραβατον ἱερωσυνην, a priesthood that passeth not away from him; he lives for ever, and he lives a priest for ever.
