And when he got into the boat, his disciples followed him. And behold, there arose a great storm on the sea, so that the boat was being swamped by the waves; but he was asleep. And they went and woke him, saying, “Save us, Lord; we are perishing.” And he said to them, “Why are you afraid, O you of little faith?” Then he rose and rebuked the winds and the sea, and there was a great calm.
Matthew 8:23-26
