But I say to you that for every idle word men may speak, they will give account of it in the day of judgment. For by your words you will be justified, and by your words you will be condemned. Matthew 12:36-37

Whoever guards his mouth and tongue Keeps his soul from troubles. Proverbs 21:23

A man’s stomach shall be satisfied from the fruit of his mouth; From the produce of his lips he shall be filled. Death and life are in the power of the tongue, And those who love it will eat its fruit. Proverbs 18:20-21
