The earthquake, the rolling away of the stone by an angel, and the fright of the Roman watchers

Mat 28:2-4
2 And there was a great earth-shock; for an angel of the Lord came down from heaven and, rolling back the stone, took his seat on it.
3 His form was shining like the light, and his clothing was white as snow:
4 And for fear of him the watchmen were shaking, and became as dead men.
