'Fierceness' in the Bible

The great city was divided into three parts, and the cities of the nations fell. Babylon the great was remembered in the sight of God, to give to her the cup of the wine of the fierceness of his wrath.

Out of his mouth proceeds a sharp, double-edged sword, that with it he should strike the nations. He will rule them with an iron rod. He treads the winepress of the fierceness of the wrath of God, the Almighty.
