Wisdom says about: fool, wise man listens to advice vs 15, prudent man, truthful witness, reckless words, tongue of the wise, truthful lips, deceit in the hearts of those who plot evil vs 20, joy for those who promote peace vs 20.
Proverbs 12:15-20
[15]Stupid people always think they are right. Wise people listen to advice.
[16]When a fool is annoyed, he quickly lets it be known. Sensible people will ignore an insult.
[17]When you tell the truth, justice is done, but lies lead to injustice.
[18]Thoughtless words can wound as deeply as any sword, but wisely spoken words can heal.
[19]A lie has a short life, but truth lives on for ever.
[20]Those who plan evil are in for a rude surprise, but those who work for good will find happiness.
