Which of the prophets ... - The interrogative form here is a strong mode of saying that they had persecuted "all" the prophets. It was "the characteristic of the nation" to persecute the messengers of God. This is not to be taken as literally and universally true; but it was a general truth; it was the national characteristic. See the notes on Matthew 21:33-40; Matthew 23:29-35.

And they have slain them ... - That is, they have slain the prophets, whose main message was that the Messiah was to come. It was a great aggravation of their offence that they put to death the messengers which foretold the greatest blessing that the nation could receive.

The Just One - The Messiah. See the notes on Acts 3:14.

Of whom ye ... - You thus show that you resemble those who rejected and put to death the prophets. You have even gone beyond them in guilt, because you have put the Messiah himself to death.

The betrayers - They are called "betrayers" here because they employed Judas to betray him - agreeable to the maxim in law, "He who does anything by another is held to have done it himself."

Which of the prophets have not your fathers persecuted? - Ye have not only resisted the Holy Ghost, but ye have persecuted all those who have spoken to you in his name, and by his influence: thus ye prove your opposition to the Spirit himself, by your opposition to every thing that proceeds from him.

They have slain them, etc. - Isaiah, who showed before of the coming of Christ, the Jews report, was sawn asunder at the command of Manasseh.

The coming of the Just One - Του δικαιου, Meaning Jesus Christ; emphatically called the just or righteous person, not only because of the unspotted integrity of his heart and life, but because of his plenary acquittal, when tried at the tribunal of Pilate: I find no fault at all in him. The mention of this circumstance served greatly to aggravate their guilt. The character of Just One is applied to our Lord in three other places of Scripture: Acts 3:14; Acts 22:14; and James 5:6.

The betrayers and murderers - Ye first delivered him up into the hands of the Romans, hoping they would have put him to death; but, when they acquitted him, then, in opposition to the declaration of his innocence, and in outrage to every form of justice, ye took and murdered him. This was a most terrible charge; and one against which they could set up no sort of defense. No wonder, then, that they were instigated by the spirit of the old destroyer, which they never resisted, to add another murder to that of which they had been so recently guilty.

Which of the prophets have not your fathers persecuted?.... Either by reviling and speaking all manner of evil of them, Matthew 5:11 or by killing them, Matthew 23:31 and they have slain them; as Isaiah, Zachariah, and others:

which showed before of the coming of the just one; of Jesus the Messiah, whose character in the prophecies of the Old Testament is righteous servant, righteous branch, just, and having salvation; and whom Stephen styles so partly on account of the holiness of his nature, and the innocence and harmlessness of his life; and partly because he is the author of righteousness, and the end of the law for it to all that believe; of whose coming in the flesh all the prophets more or less spoke: and this being good news, and glad tidings, made the sin of the Jewish fathers the greater, in putting them to death, as the innocent character of Christ was an aggravation of the Jews' sin, in murdering of him, as it follows:

of whom ye have been now the betrayers and murderers; Judas, one of their nation, betrayed him into the hands of the chief priests and elders; and they betrayed, or delivered him into the hands of Pontius Pilate to be condemned to death, which they greatly importuned, and would not be satisfied without; and therefore are rightly called the murderers, as well as the betrayers of him.

Which of the prophets have not your fathers persecuted? and they have slain them which shewed before of the coming of the Just One; of whom ye have been now the betrayers and murderers:

7:52 Which of the prophets, etc.? Their fathers habitually persecuted the prophets and slew some of them who predicted Christ (see lives of Isaiah and Jeremiah). Now they, his hearers, were murderers of the Just One.

52. Which of, &c.-Deadly hostility to the messengers of God, whose high office it was to tell of "the Righteous One," that well-known prophetic title of Messiah (Isa 53:11; Jer 23:6, &c.), and this consummated by the betrayal and murder of Messiah Himself, on the part of those now sitting in judgment on the speaker, are the still darker features of the national character depicted in these withering words.

7:51-53 Stephen was going on, it seems, to show that the temple and the temple service must come to an end, and it would be the glory of both to give way to the worship of the Father in spirit and in truth; but he perceived they would not bear it. Therefore he broke off, and by the Spirit of wisdom, courage, and power, sharply rebuked his persecutors. When plain arguments and truths provoke the opposers of the gospel, they should be shown their guilt and danger. They, like their fathers, were stubborn and wilful. There is that in our sinful hearts, which always resists the Holy Ghost, a flesh that lusts against the Spirit, and wars against his motions; but in the hearts of God's elect, when the fulness of time comes, this resistance is overcome. The gospel was offered now, not by angels, but from the Holy Ghost; yet they did not embrace it, for they were resolved not to comply with God, either in his law or in his gospel. Their guilt stung them to the heart, and they sought relief in murdering their reprover, instead of sorrow and supplication for mercy.
