Proverbs 13:3

1 A wise son heeds his father’s discipline, but a mocker does not listen to rebuke.

2 From the fruit of his lips a man enjoys good things, but the desire of the faithless is violence.

He who guards his mouth protects his life, but the one who opens his lips invites his own ruin.

4 The slacker craves yet has nothing, but the soul of the diligent is fully satisfied.

5 The righteous hate falsehood, but the wicked bring shame and disgrace.

Do read the surrounding verses too, because the context often says more than a single verse.
