'Fierceness' in the Bible

but a certain fearful expectation of judgment, and a fierceness of fire which shall devour the adversaries.

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

And out of his mouth proceedeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness of the wrath of God, the Almighty.
