Matthew 27:52-54
27:52 And tombs were opened, and the bodies of many saints who had died were raised.
27:53 (They came out of the tombs after his resurrection and went into the holy city and appeared to many people.)
27:54 Now when the centurion and those with him who were guarding Jesus saw the earthquake and what took place, they were extremely terrified and said, “Truly this one was God’s Son!”
