John 6:17-19

17 And entered into a ship, and went over the sea toward Capernaum. And it was now dark, and Jesus was not come to them.

18 And the sea arose by reason of a great wind that blew.

19 So when they had rowed about five and twenty or thirty furlongs, they see Jesus walking on the sea, and drawing nigh unto the ship: and they were afraid.
