Mark 4:37-40

And a fierce windstorm began to blow, and waves were breaking over the boat, so that it was already being swamped. But Jesus was in the stern, asleep [with His head] on the [sailor’s leather] cushion. And they woke Him and said to Him, “Teacher, do You not care that we are about to die?” And He got up and [sternly] rebuked the wind and said to the sea, “Hush, be still (muzzled)!” And the wind died down [as if it had grown weary] and there was [at once] a great calm [a perfect peacefulness]. Jesus said to them, “Why are you afraid? Do you still have no faith and confidence [in Me]?”
