John 6:18-20 King James Version (KJV)
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.
John 6:18-20 Amplified Bible, Classic Edition (AMPC)
18 Meanwhile, the sea was getting rough and rising high because of a great and violent wind that was blowing.
19 [However] when they had rowed three or four miles, they saw Jesus walking on the sea and approaching the boat. And they were afraid (terrified).
20 But Jesus said to them, It is I; be not afraid! [I Am; stop being frightened!]
