Mark 4:37-39 NIV

[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.
