"And when Jesus had cried out again in a loud voice, he gave up his spirit.
At that moment the curtain of the temple was torn in two from top to bottom. The earth shook and the rocks split. The tombs broke open and the bodies of many holy people who had died were raised to life. They came out of the tombs, and after Jesus' resurrection they went into the holy city and appeared to many people. When the centurion and those with him who were guarding Jesus saw the earthquake and all that had happened, they were terrified, and exclaimed, "Surely he was the Son of God!"
