Matthew 8:26  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.

and the turmoil of the nations

Isaiah 17:12-13  Woe to the many nations that rage--they rage like the raging sea! Woe to the peoples who roar--they roar like the roaring of great waters! Although the peoples roar like the roar of surging waters, when he rebukes them they flee far away, driven before the wind like chaff on the hills, like tumbleweed before a gale.
