'Walking on the Sea' in the Bible

but when he saw them buffeted as they rowed (for the wind was against them) he went to them about the fourth watch of the night walking on the sea. He meant to pass them,

but when they saw him walking on the sea they thought it was a ghost and shrieked aloud ??50 for they all saw him and were terrified. Then he spoke to them at once; "Courage," he said, "it is I, have no fear."
