Matthew 27:51-53 Matthew 27:51-53 [51] And, behold, the veil of the temple was rent in two from the top to the bottom; and the earth did quake, and the rocks rent; [52] And the graves were opened; and many bodies of the saints which slept arose, [53] And came out of the graves after his resurrection, and went into the holy city, and appeared to many.
American King James Version×tells us what happened right after Jesus Christ died: "Then, behold, the veil of the temple was torn in two from top to bottom; and the earth quaked, and the rocks were split, and the graves were opened; and many bodies of the saints who had fallen asleep were raised; and coming out of the graves after His resurrection, they went into the holy city and appeared to many."

This resurrection of several believers was one of the phenomena accompanying the resurrection of Jesus Christ to underscore that monumental event. These saints came back to physical life. (In the Bible, the word saints means those who are sanctified or set apart as holy, meaning all of God's true followers.) We know from such scriptures as 1 Thessalonians 4:15-17 1 Thessalonians 4:15-17 [15] For this we say to you by the word of the Lord, that we which are alive and remain to the coming of the Lord shall not prevent them which are asleep. [16] For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: [17] Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
American King James Version×and 1 Corinthians 15:51-52 1 Corinthians 15:51-52 [51] Behold, I show you a mystery; We shall not all sleep, but we shall all be changed, [52] In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
American King James Version×that God has resurrected no one to eternal life as an immortal spirit yet—except Christ.

For example, 1 Thessalonians 4:15-17 1 Thessalonians 4:15-17 [15] For this we say to you by the word of the Lord, that we which are alive and remain to the coming of the Lord shall not prevent them which are asleep. [16] For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: [17] Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
American King James Version×says: "For this we say to you by the word of the Lord, that we who are alive and remain until the coming of the Lord will by no means precede those who are asleep. For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God. And the dead in Christ will rise first. Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord."

These references teach us that God will change the righteous dead along with living Christians to immortal beings when Jesus Christ returns.

After God brought the people mentioned in Matthew 27:52-53 Matthew 27:52-53 [52] And the graves were opened; and many bodies of the saints which slept arose, [53] And came out of the graves after his resurrection, and went into the holy city, and appeared to many.
American King James Version×back to life, they undoubtedly went back to their homes, where many acquaintances saw them. It's hard to imagine how utterly startling such an experience would be for their relatives and friends!

The Bible says nothing further about these people God resurrected at Christ's death, leaving us to conclude that they eventually died (again) and their families buried them (again). Along with all other saints who died, they await in their graves their resurrection to spirit life.
