matthew 27:52 And the graves were opened; and many bodies of the saints which slept arose, - Free Bible Online

      52. And the graves were opened; and many bodies of the saints which slept arose--These sleeping saints (see on 1Th 4:14) were Old Testament believers, who--according to the usual punctuation in our version--were quickened into resurrection life at the moment of their Lord's death, but lay in their graves till His resurrection, when they came forth. But it is far more natural, as we think, and consonant with other Scriptures, to understand that only the graves were opened, probably by the earthquake, at our Lord's death, and this only in preparation for the subsequent exit of those who slept in them, when the Spirit of life should enter into them from their risen Lord, and along with Him they should come forth, trophies of His victory over the grave. Thus, in the opening of the graves at the moment of the Redeemer's expiring, there was a glorious symbolical proclamation that the death which had just taken place had "swallowed up death in victory"; and whereas the saints that slept in them were awakened only by their risen Lord, to accompany Him out of the tomb, it was fitting that "the Prince of Life . . . should be the First that should rise from the dead" (Ac 26:23; 1Co 15:20, 23; Col 1:18; Re 1:5).
      and went into the holy city--that city where He, in virtue of whose resurrection they were now alive, had been condemned.
      and appeared unto many--that there might be undeniable evidence of their own resurrection first, and through it of their Lord's. Thus, while it was not deemed fitting that He Himself should appear again in Jerusalem, save to the disciples, provision was made that the fact of His resurrection should be left in no doubt. It must be observed, however, that the resurrection of these sleeping saints was not like those of the widow of Nain's son, of Jairus' daughter, of Lazarus, and of the man who "revived and stood upon his feet," on his dead body touching the bones of Elisha (2Ki 13:21) --which were mere temporary recallings of the departed spirit to the mortal body, to be followed by a final departure of it "till the trumpet shall sound." But this was a resurrection once for all, to life everlasting; and so there is no room to doubt that they went to glory with their Lord, as bright trophies of His victory over death.
