'Fierce Anger' in the Bible

and say unto him, Take heed, and be quiet; fear not, neither let thy heart be faint, because of these two tails of smoking firebrands, for the fierce anger of Rezin and Syria, and of the son of Remaliah.

Behold, the day of Jehovah cometh, cruel, with wrath and fierce anger; to make the land a desolation, and to destroy the sinners thereof out of it.

Therefore I will make the heavens to tremble, and the earth shall be shaken out of its place, in the wrath of Jehovah of hosts, and in the day of his fierce anger.
