"And behold, there was a great earthquake; for an angel of the Lord descended from heaven, approached, rolled back the stone and sat upon it. His appearance was like lightning and his clothing was white as snow. The guards were shaken with fear of him and became like dead men. Then the angel said to the women in reply, 'Do not be afraid! I know that you are seeking Jesus the crucified. He is not here, for he has been raised just as he said.'"
Matthew 28: 2-6
