Matthew 8:23-26

23And he went on board ship and his disciples followed him;

24and behold, [the water] became very agitated on the sea, so that the ship was covered by the waves; but he slept.

25And the disciples came and awoke him, saying, Lord save: we perish.

26And he says to them, Why are ye fearful, O ye of little faith? Then, having arisen, he rebuked the winds and the sea, and there was a great calm.
