Proverbs 13:1-4, The Use of the Mouth 

Proverbs 13:1-4 A wise son hears his father's instruction, but a scoffer does not listen to rebuke. From the fruit of his mouth a man eats what is good, but the desire of the treacherous is for violence. Whoever guards his mouth preserves his life; he who opens wide his lips comes to ruin. The soul of the sluggard craves and gets nothing, while the soul of the diligent is richly supplied.
