23 Then he got into the boat and his disciples followed him. 24 Suddenly a furious storm came up on the lake, so that the waves swept over the boat. But Jesus was sleeping. 25The disciples went and woke him, saying, “Lord, save us! We’re going to drown!”
26 He replied, “You of little faith, why are you so afraid?” Then he got up and rebuked the winds and the waves, and it was completely calm.
27 The men were amazed and asked, “What kind of man is this? Even the winds and the waves obey him!”
Matthew 8:23-27 (NIV)
35 That day when evening came, he said to his disciples, “Let us go over to the other side.” 36 Leaving the crowd behind, they took him along, just as he was, in the boat. There were also other boats with him. 37 A furious squall came up, and the waves broke over the boat, so that it was nearly swamped. 38 Jesus was in the stern, sleeping on a cushion. The disciples woke him and said to him, “Teacher, don’t you care if we drown?”
39 He got up, rebuked the wind and said to the waves, “Quiet! Be still!” Then the wind died down and it was completely calm.
40 He said to his disciples, “Why are you so afraid? Do you still have no faith?”
41 They were terrified and asked each other, “Who is this? Even the wind and the waves obey him!”
Mark 4:35-41 (NIV)
