Mark 4:37-39

37A furious squall came up, and the waves broke over the boat, so that it was nearly swamped.

38Jesus was in the stern, sleeping on a cushion. The disciples woke him and said to him, “Teacher, don’t you care if we drown?”

39He got up, rebuked the wind and said to the waves, “Quiet! Be still!” Then the wind died down and it was completely calm.
