'Fierceness' in the Bible

Is it nothing to you, all ye passing by the way? Look attentively, and see, If there is any pain like my pain, That He is rolling to me? Whom Jehovah hath afflicted In the day of the fierceness of His anger.

Completed hath Jehovah His fury, He hath poured out the fierceness of His anger, And he kindleth a fire in Zion, And it devoureth her foundations.
