Matthew 27:51-53 (New International Version)

 ⁵¹At that moment the curtain of the temple was torn in two from top to bottom. The earth shook and the rocks split. ⁵²The tombs broke open and the bodies of many holy people who had died were raised to life. ⁵³They came out of the tombs, and after Jesus' resurrection they went into the holy city and appeared to many people.
