Mark 6:47-50 King James Version (KJV)
47 And when even was come, the ship was in the midst of the sea, and he alone on the land.
48 And he saw them toiling in rowing; for the wind was contrary unto them: and about the fourth watch of the night he cometh unto them, walking upon the sea, and would have passed by them.
49 But when they saw him walking upon the sea, they supposed it had been a spirit, and cried out:
50 For they all saw him, and were troubled. And immediately he talked with them, and saith unto them, Be of good cheer: it is I; be not afraid.
Mark 6:47-50 Amplified Bible, Classic Edition (AMPC)
47 Now when evening had come, the boat was out in the middle of the lake, and He was by Himself on the land.
48 And having seen that they were troubled and tormented in [their] rowing, for the wind was against them, about the fourth watch of the night [between 3:00-6:00 a.m.] He came to them, walking [directly] on the sea. And He acted as if He meant to pass by them,
49 But when they saw Him walking on the sea they thought it was a ghost, and [a]raised a [deep, throaty] shriek of terror.
50 For they all saw Him and were agitated (troubled and filled with fear and dread). But immediately He talked with them and said, Take heart! I Am! Stop being alarmed and afraid.
Mark 6:47-50 Living Bible (TLB)
47 During the night, as the disciples in their boat were out in the middle of the lake, and he was alone on land, 48 he saw that they were in serious trouble, rowing hard and struggling against the wind and waves.
About three o’clock in the morning he walked out to them on the water. He started past them, 49 but when they saw something walking along beside them, they screamed in terror, thinking it was a ghost, 50 for they all saw him.
But he spoke to them at once. “It’s all right,” he said. “It is I! Don’t be afraid.”
