'Fierce Anger' in the Bible

Then Amaziah separated them, [namely], the army that came to him out of Ephraim, to go home again. Therefore their anger was greatly kindled against Judah, and they returned home in fierce anger.

Now it is in my heart to make a covenant with LORD, the God of Israel, that his fierce anger may turn away from us.

Now be ye not stiff-necked, as your fathers were, but yield yourselves to LORD, and enter into his sanctuary, which he has sanctified forever, and serve LORD your God, that his fierce anger may turn away from you.
