And entering the tomb, they saw a young man sitting on the right side, dressed in a white robe, and they were alarmed.  
And he said to them, “Do not be alarmed.
You seek Jesus of Nazareth, who was crucified.  He has risen; he is not here.  See the place where they laid him.  But go, tell his disciples and Peter that he is going before you to Galilee.  There you will see him, just as he told you.”

(Mark 16:5-7 -- ESV)
