when suddenly a great earthquake occurred. For an angel of the Lord descended from heaven, and came and rolled away the stone, and seated himself on it.

There was a great earthquake - Rather there "had been." It does not mean that this was while they were there, or while they were going, but that there "had been" so violent a commotion as to remove the stone. The word rendered here as "earthquake" does not of necessity mean that the convulsion extended to the earth, but only that there had been such a concussion as to remove the stone.
And sat upon it - Sat upon it when the keepers saw him, Matthew 28:4. It is not said that he was sitting when he appeared to the women. From Luke it would rather appear that he was standing.

A great earthquake - Σεισμος, a shaking or commotion of any kind: probably the word means no more than the confusion caused among the guards by the angel's appearance. All this had taken place before the women reached the sepulchre.
The angel of the Lord descended from heaven - Matthew is very particular in this, to show that the word angel is not to be taken in the sense of an ordinary messenger, who might have come from Joseph of Arimathea, or from any other; but in the sense of an extraordinary messenger, who descended from God, out of heaven, for this very purpose. It is likely that the angel had descended, rolled away the stone, and was sitting on it, before the women reached the tomb.

And behold there was a great earthquake,.... Or "there had been one"; which, how far it reached, and whether further than the spot of ground in which the sepulchre was, is not certain: it was an emblem of the shaking of the earth by the preaching of the Gospel, the sound of which was now to go after Christ's resurrection to the ends of the world; and a prelude of the general resurrection, when the earth shall be shaken, and the graves opened, and the dead come forth; and was a symbol and token of the presence and majesty of Christ, at whose rising, as at his death, the earth shook and trembled. Think whether the watch could now be asleep, as they afterwards gave out, Matthew 28:13. The Persic version renders it very wrongly; "and there was great consternation and fear"; which was the consequence of the earthquake, and the descent of the angel, and was so great that it was not possible for the keepers to sleep, if ever so much inclined:
for the angel of the Lord descended from heaven; perhaps Gabriel, who brought the news of the conception of Christ to the virgin, and of his incarnation to the shepherds, and might be the same angel that strengthened him in the garden: nor is this any contradiction to the other evangelists, which speak of two angels, Luke 24:4, for Matthew does not say there were no more than one, though he makes mention but of one.
And came and rolled back the stone from the door; of the sepulchre, which by Joseph, or his orders, was put there, and was sealed by the Jews. This might be done, that way might be made for the risen body of Christ to pass out of the sepulchre; for to suppose, as some do, that he penetrated through this stone with his risen body, is not to be credited: it is true, he could have caused the stone to have given way, or removed it himself, and put it in the place again; as he caused the doors of the house in which the disciples were, to open and shut so quick, that they could not discern it when he appeared in the midst of them, John 20:19; see Acts 12:10, but he might choose to do it by the ministry of an angel, which is no ways derogatory to his power and majesty, but rather agreeable. Moreover, this might be done, that the women might have access to the sepulchre, and enter into it, which was the thing they were concerned about by the way, who should roll away the stone for them. Besides, this the angel did, as a token that Christ was risen, and to let the guard know as much, who, if they thought fit, might come and see what was done; but chiefly the stone was rolled away by the angel, as an emblem of the acquittance and discharge of Christ, as the surety of his people. He had taken upon him their sins; he had bore them in his body on the tree; he had suffered and died for them, and was laid as a prisoner in the grave; and now full satisfaction being made, an angel is sent from heaven to roll away the stone; thereby signifying, that the debt was fully paid, and he was now legally discharged. It is added,
and sat upon it; thereby showing who it was that rolled it away; that it was done by him, not by the earthquake, nor by any human power: he sat there defying the guard of soldiers to come nigh; and waiting for the coming of the women, to tell them the good news, that their Lord was risen; and as the keeper of the sepulchre, that no corpse might be brought and laid in the room of Christ, and it be said that he was not risen. This posture of the angel does not contradict what other evangelists say of this, and the other angel, that they stood by the women, and also were sitting in the sepulchre, Mark 16:5, for each was true: when the women first came, the angel sat upon the stone; after that, with the other, stood by them; when having invited them to the grave, placed themselves, sitting the one at the head, and the other at the feet, where the body of Christ had lain.

Behold, there was a great earthquake. The word rendered "earthquake" is rendered tempest in Matthew 8:24. It means a "commotion." It is not needful to decide that there was more than a local disturbance.
For the angel of the Lord descended. An angel. There is no article. All the gospels speak of the angelic appearance at the tomb, though some give details omitted by others.
Rolled back the stone. The commotion, or earthquake, accompanied the rolling back of the stone. "It was not for him to whom (John 20:19-20) the stone was no hindrance, but for the women and disciples that it was rolled away."--Alford.

An angel of the Lord had rolled away the stone and sat upon it - St. Luke and St. John speak of two angels that appeared: but it seems as if only one of them had appeared sitting on the stone without the sepulchre, and then going into it, was seen with another angel, sitting, one where the head, the other where the feet of the body had lain.
