Mark 6:48-50

King James Version

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.
