Matthew 12:35

⁶Let your speech always be with grace, seasoned with salt, that you may know how you ought to answer each one.

⁴A gentle tongue is a tree of life, but deceit in it crushes the spirit.

²⁸The heart of the righteous weighs answers, but the mouth of the wicked gushes out evil.

¹⁶Let the word of Christ dwell in you richly; in all wisdom teaching and admonishing one another with psalms, hymns, and spiritual songs, singing with grace in your heart to the Lord.

¹¹A word fitly spoken is like apples of gold in settings of silver. ¹²As an earring of gold, and an ornament of fine gold, so is a wise reprover to an obedient ear.

³⁴You offspring of vipers, how can you, being evil, speak good things? For out of the abundance of the heart, the mouth speaks.

²¹The wise in heart shall be called prudent. Pleasantness of the lips promotes instruction. ²²Understanding is a fountain of life to one who has it, but the punishment of fools is their folly. ²³The heart of the wise instructs his mouth, and adds learning to his lips.

²⁰The tongue of the righteous is like choice silver. The heart of the wicked is of little worth. ²¹The lips of the righteous feed many, but the foolish die for lack of understanding.

²⁹Let no corrupt speech proceed out of your mouth, but only what is good for building others up as the need may be, that it may give grace to those who hear.

³⁰The mouth of the righteous talks of wisdom. His tongue speaks justice. ³¹The law of his God is in his heart. None of his steps shall slide.
