He rebuked the wind.
He said to the sea.
Then the wind ceased.
There was a dead calm.”
καὶ διεγερθεὶς ἐπετίμησεν τῷ ἀνέμῳ καὶ εἶπεν τῇ θαλάσσῃ Σιώπα, πεφίμωσο. καὶ ἐκόπασεν ὁ ἄνεμος, καὶ ἐγένετο γαλήνη μεγάλη.
This response of Jesus can be found in Matthew, chapter 8:26, and Luke, chapter 8:24, in a somewhat similar manner. Mark said that after Jesus woke up (καὶ διεγερθεὶς), he then rebuked or admonished (ἐπετίμησεν) the wind (τῷ ἀνέμῳ). Then he spoke to the sea itself (καὶ τῇ θαλάσσῃ), as he told the sea to be silent, peaceful, and still (Σιώπα, πεφίμωσο). Thus, the wind abated or was still (αὶ ἐκόπασεν ὁ ἄνεμος) and there was a great calmness in the sea (καὶ ἐγένετο γαλήνη μεγάλη).
