Proverbs 15:28

But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear:

A fool uttereth all his mind: but a wise man keepeth it in till afterwards.

Be not rash with thy mouth, and let not thine heart be hasty to utter any thing before God: for God is in heaven, and thou upon earth: therefore let thy words be few.

The tongue of the wise useth knowledge aright: but the mouth of fools poureth out foolishness.

The heart of the wise teacheth his mouth, and addeth learning to his lips.

O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.

In the multitude of words there wanteth not sin: but he that refraineth his lips is wise.

Seest thou a man that is hasty in his words? there is more hope of a fool than of him.

Suffer not thy mouth to cause thy flesh to sin; neither say thou before the angel, that it was an error: wherefore should God be angry at thy voice, and destroy the work of thine hands?

Every prudent man dealeth with knowledge: but a fool layeth open his folly.

For when they speak great swelling words of vanity, they allure through the lusts of the flesh, through much wantonness, those that were clean escaped from them who live in error.
