Be angry the scripture teaches but then it says “sin not” What does it mean by “sin not”? It means don’t be hasty to speak when angry. Words spoken in anger have never produced anything good. You will regret it.
Psalm 39:1 says “I said I will take heed to my ways that I sin not with my tongue…”
Keep yourself from speaking those words in anger. You may receive applause from men but time will reveal the foolishness in hasty speech.
This is why scripture says “be quick to hear, slow to speak and slow to wrath” Be slow to speak when angry.
