John 6:15-21

(15) When Jesus therefore perceived that they would come and take him by force, to make him a king, he departed again into a mountain himself alone.  (16)  And when even was now come, his disciples went down unto the sea,  (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.  (20)  But he saith unto them, It is I; be not afraid.  (21)  Then they willingly received him into the ship: and immediately the ship was at the land whither they went.
