John 6:16-19 NIV

[16] When evening came, his disciples went down to the lake, [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.
