John 6:15-21 King James Version (KJV)
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.
