'Angry' in the Bible

Never let your mouth cause you to sin and don't proclaim in the presence of the angel, "My promise was a mistake," for why should God be angry at your excuse and destroy what you've undertaken?

Never be in a hurry to become internally angry, since anger settles down in the lap of fools.

If your overseer gets angry at you, don't resign, because calmness pacifies great offenses.
