John 6:17-21 New International Version (NIV)

17. where they got into a boat and set off across the lake for Capernaum. By now it was dark, and Jesus had not yet joined them.

18. A strong wind was blowing and the waters grew rough.

19. When they had rowed about three or four miles, they saw Jesus approaching the boat, walking on the water; and they were frightened.

20. But he said to them, “It is I; don’t be afraid.”

21. Then they were willing to take him into the boat, and immediately the boat reached the shore where they were heading.
