'Roaring' in the Bible

"There will be signs in the sun, the moon, and the stars, and there will be distress on earth among the nations that are confused by the roaring of the sea and its waves.

Be clear-minded and alert. Your opponent, the Devil, is prowling around like a roaring lion, looking for someone to devour.

But the Day of the Lord will come like a thief. On that day the heavens will disappear with a roaring sound, the elements will be destroyed by fire, and the earth and everything done on it will be exposed.
