So also Christ glorified not himself; - see the notes at John 8:54. The meaning is, that Jesus was not ambitious; that he did not obtrude himself into the great office of high priest; he did not enter upon its duties without being regularly called to it. Paul claimed that Christ held that office; but, as he was not descended front Aaron, and as no one might perform its duties without being regularly called to it, it was incumbent on him to show that Jesus was not an intruder, but had a regular vocation to that work. This he shows by a reference to two passages of the Old Testament.

But he that said unto him - That is, he who said to him "Thou art my Son," exalted him to that office. He received his appointment from him. This was decisive in the case, and this was sufficient, if it could be made out, for the only claim which Aaron and his successors could have to the office, was the fact that they had received their appointment front God.

Thou art my Son - Psalm 2:7. See this passage explained in the notes on Acts 13:38. It is used here with reference to the designation to the priestly office, though in the Psalm more particularly to the anointing to the office of king. The propriety of this application is founded on the fact that the language in the Psalm is of so general a character, that it may be applied to "any" exaltation of the Redeemer, or to any honor conferred on him. It is used here with strict propriety, for Paul is saying that Jesus did not exalt "himself," and in proof of that he refers to the fact that God had exalted him by calling him his "Son."

Christ glorified not himself - The man Jesus Christ, was also appointed by God to this most awful yet glorious office, of being the High Priest of the whole human race. The Jewish high priest represented this by the sacrifices of beasts which he offered; the Christian High Priest must offer his own life: Jesus Christ did so; and, rising from the dead, he ascended to heaven, and there ever appeareth in the presence of God for us. Thus he has reassumed the sacerdotal office; and because he never dies, he can never have a successor. He can have no vicars, either in heaven or upon earth; those who pretend to be such are impostors, and are worthy neither of respect nor credit.

Thou art my Son - See on Hebrews 1:5 (note), and the observations at the end of that chapter. And thus it appears that God can have no high priest but his Son; and to that office none can now pretend without blasphemy, for the Son of God is still the High Priest in his temple.

So also Christ glorified not himself to be made an high priest,.... It was a glorifying of Christ, to make him an high priest; not as God, for as such no addition can be made to his glory; yea, it was a condescension in him to become a priest: but as man; it was an honour to the human nature to be united to the Son of God; and to be separated from others to this office; and to be called unto it, qualified for it, and invested with it; and to be of the order he was, and to do the work; and the very assistance he had in it, for the accomplishment of it, was a glorifying of him, for which he prayed; and the work being done, he had glory given him by his Father; and an ascription of glory is made to him by angels and saints: but Christ did not take this high and honourable office to himself, nor the glory of it; indeed, he did not receive it from man, nor was he made a priest according to the ceremonial law; yet he did not intrude himself into this office:

but he that said unto him, thou art my Son, today have I begotten thee; he appointed him to this office; he sent him to execute it; he anointed him with the oil of gladness above his fellows; he consecrated and established him in it with an oath; and prescribed to him what he should do, suffer, and offer; and declared to him what he might expect as the reward thereof. These words are taken out of Psalm 2:7; see Gill on Hebrews 1:5, and they are not to be considered as constitutive of Christ's priesthood, as if that was intended by the begetting of him as a Son; but as descriptive of the person, who called him to it, who stood in the relation of a Father to Christ, and Christ in the relation of a Son to him; therefore the one was very proper to call, and the other a very fit person to be called to this office, being every way capable of executing it, to the glory of God, and to the good of men.

Did not glorify himself to be made high priest

Ἐδόξασεν glorified is general, and is more specifically defined by γενηθῆναι ἀρχιερέα to be made high priest.

But he that said unto him, Thou art my Son, etc.

Supply glorified him. He did not glorify himself, but God who styled him "son" glorified him. Thou art my Son is introduced thus in close connection with the call to the priesthood, in recognition of the fact that the priesthood of Christ had its basis in his sonship. "Christ's priestly vocation ceases to be an accident in his history, and becomes an essential characteristic of his position as Son: sonship, christhood, priestliness, inseparably interwoven" (Bruce).

So also Christ glorified not himself to be made an high priest; but he that said unto him, Thou art my Son, to day have I begotten thee.

5:5 So also Christ glorified not himself to be made an high priest. Did not take the office of himself, but God called him to his priesthood. The time is pointed out when he was so called.

But he that said unto him. It was when God said, in Ps 2:7,

Thou art my son, to day have I begotten thee. This refers to when Christ was begotten from the dead, the first-born of the new creation. See Eph 1:20-23. At this time he entered fully, at the call of God, upon his high priesthood in behalf of men.

5:5 So also Christ glorified not himself to be an high priest - That is, did not take this honour to himself, but received it from him who said, Thou art my Son, this day have I begotten thee - Not, indeed, at the same time; for his generation was from eternity. Psa 2:7.

5. glorified not himself-did not assume the glory of the priestly office of Himself without the call of God (Joh 8:54).

but he that said-that is, the Father glorified Him or appointed Him to the priesthood. This appointment was involved in, and was the result of, the Sonship of Christ, which qualified Him for it. None but the divine Son could have fulfilled such an office (Heb 10:5-9). The connection of Sonship and priesthood is typified in the Hebrew title for priests being given to David's sons (2Sa 8:18). Christ did not constitute Himself the Son of God, but was from everlasting the only-begotten of the Father. On His Sonship depended His glorification, and His being called of God (Heb 5:10), as Priest.

5:1-10 The High Priest must be a man, a partaker of our nature. This shows that man had sinned. For God would not suffer sinful man to come to him alone. But every one is welcome to God, that comes to him by this High Priest; and as we value acceptance with God, and pardon, we must apply by faith to this our great High Priest Christ Jesus, who can intercede for those that are out of the way of truth, duty, and happiness; one who has tenderness to lead them back from the by-paths of error, sin, and misery. Those only can expect assistance from God, and acceptance with him, and his presence and blessing on them and their services, that are called of God. This is applied to Christ. In the days of his flesh, Christ made himself subject to death: he hungered: he was a tempted, suffering, dying Jesus. Christ set an example, not only to pray, but to be fervent in prayer. How many dry prayers, how few wetted with tears, do we offer up to God! He was strengthened to support the immense weight of suffering laid upon him. There is no real deliverance from death but to be carried through it. He was raised and exalted, and to him was given the power of saving all sinners to the uttermost, who come unto God through him. Christ has left us an example that we should learn humble obedience to the will of God, by all our afflictions. We need affliction, to teach us submission. His obedience in our nature encourages our attempts to obey, and for us to expect support and comfort under all the temptations and sufferings to which we are exposed. Being made perfect for this great work, he is become the Author of eternal salvation to all that obey him. But are we of that number?
