Mark 6:48-50

48He saw them straining at the oars, because the wind was against them. As the night was ending, he came to them walking on the sea, for he wanted to pass by them.

49When they saw him walking on the water they thought he was a ghost. They cried out,

50for they all saw him and were terrified. But immediately he spoke to them: “Have courage! It is I. Do not be afraid.”
