'Anger' in the Bible

For God's anger is being revealed from Heaven against all impiety and against the iniquity of men who through iniquity suppress the truth. God is angry:

The fact is that in the stubbornness of your impenitent heart you are treasuring up against yourself anger on the day of Anger--the day when the righteousness of God's judgements will stand revealed.

but wrath and anger to those who live in selfish ambition and do not obey the truth but follow unrighteousness.

If therefore we have now been pronounced free from guilt through His blood, much more shall we be delivered from God's anger through Him.

What if God, although willing to show His [terrible] wrath and to make His power known, has tolerated with great patience the objects of His wrath [which are] prepared for destruction?

But I say, Did not Israel know? First Moses saith, I will provoke you to jealousy by them that are no people, and by a foolish nation I will anger you.

Do not be revengeful, my dear friends, but give way before anger; for it is written, "'Revenge belongs to Me: I will pay back,' says the Lord."
