And the graves were opened,.... Which were near the city of Jerusalem: this was a proof of Christ's power over death and the grave, by dying; when he through death, destroyed him that had the power of it, and abolished death itself; and became the plague of death and the destruction of the grave, taking into his hands the keys of hell and death:

and many bodies of saints which slept, arose: not that they arose at the time of Christ's death: the graves were opened then, when the earth quaked, and the rocks were rent; but the bodies of the saints did not arise, till after Christ was risen, as appears from the following verse; but because the other event now happened, they are both recorded here: these were saints, and such as slept in Jesus; and of whom he is the first fruits that now rose; and not all, but many of them, as pledges of the future resurrection, and for the confirmation of Christ's, and the accomplishment of a prophecy in Isa 26:19. And they rose in the same bodies in which they before lived, otherwise they could not be called their bodies, or known by those to whom they appeared: but who they were is not to be known; some have thought them to be the ancient patriarchs, as Adam, Noah, Abraham, Isaac, Jacob, &c. In the Septuagint on Job 42:17, Job is said to be one of them, and a tradition is there recorded, which runs thus:

"it is written, that he rose with whom the Lord rose.

But it should seem rather, that they were some later saints, such as Zechariah, the father of John the Baptist, John the Baptist himself, good old Simeon, Joseph the husband of Mary, and others, well known to persons now alive. Some think they were such, as had been martyrs in the cause of religion; and so the Persic version renders the words, "and the bodies of many saints who suffered martyrdom, rose out of the graves".

SIGNS AND CIRCUMSTANCES FOLLOWING THE DEATH OF THE LORD JESUS--HE IS TAKEN DOWN FROM THE CROSS, AND BURIED--THE SEPULCHRE IS GUARDED. ( = Mar 15:38-47; Luk 23:47-56; Joh 19:31-42). (Mat. 27:51-66)

And, behold, the veil of the temple was rent in twain from the top to the bottom--This was the thick and gorgeously wrought veil which was hung between the "holy place" and the "holiest of all," shutting out all access to the presence of God as manifested "from above the mercy seat and from between the cherubim"--"the Holy Ghost this signifying, that the way into the holiest of all was not yet made manifest" (Heb 9:8). Into this holiest of all none might enter, not even the high priest, save once a year, on the great day of atonement, and then only with the blood of atonement in his hands, which he sprinkled "upon and before the mercy seat seven times" (Lev 16:14) --to signify that access for sinners to a holy God is only through atoning blood. But as they had only the blood of bulls and of goats, which could not take away sins (Heb 10:4), during all the long ages that preceded the death of Christ the thick veil remained; the blood of bulls and of goats continued to be shed and sprinkled; and once a year access to God through an atoning sacrifice was vouchsafed--in a picture, or rather, was dramatically represented, in those symbolical actions--nothing more. But now, the one atoning Sacrifice being provided in the precious blood of Christ, access to this holy God could no longer be denied; and so the moment the Victim expired on the altar, that thick veil which for so many ages had been the dread symbol of separation between God and guilty men was, without a hand touching it, mysteriously "rent in twain from top to bottom"--"the Holy Ghost this signifying, that the way into the holiest of all was NOW made manifest!" How emphatic the statement, from top to bottom; as if to say, Come boldly now to the Throne of Grace; the veil is clean gone; the mercy seat stands open to the gaze of sinners, and the way to it is sprinkled with the blood of Him--"who through the eternal Spirit hath offered Himself without spot to God!" Before, it was death to go in, now it is death to stay out. See more on this glorious subject on Heb 10:19-22.

An Earthquake--The Rocks Rent--The Graves Opened, that the Saints Which Slept in Them Might Come Forth after Their Lord's Resurrection (Mat 27:51-53).
and the earth did quake--From what follows it would seem that this earthquake was local, having for its object the rending of the rocks and the opening of the graves.

and the rocks rent--"were rent"--the physical creation thus sublimely proclaiming, at the bidding of its Maker, the concussion which at that moment was taking place in the moral world at the most critical moment of its history. Extraordinary rents and fissures have been observed in the rocks near this spot.
