Proverbs 29:9, 11, 20

There’s no use arguing with a fool, for his ranting and raving prevent you from making a case and settling the argument in a calm way.

You can recognize fools by the way they give full vent to their rage and let their words fly! But the wise bite their tongues and hold back all they could say.

There’s only one kind of person who is worse than a fool: the impetuous one who speaks without thinking first.
