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.

And the tongue is a fire, a world of iniquity: so is the tongue among our members, that it defileth the whole body, and setteth on fire the course of nature; and it is set on fire of hell. For every kind of beasts, and of birds, and of serpents, and of things in the sea, is tamed, and hath been tamed of mankind: But the tongue can no man tame; it is an unruly evil, full of deadly poison.

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

The words of a wise man’s mouth are gracious; but the lips of a fool will swallow up himself. The beginning of the words of his mouth is foolishness: and the end of his talk is mischievous madness. A fool also is full of words: a man cannot tell what shall be; and what shall be after him, who can tell 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?

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.

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

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

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

For there are many unruly and vain talkers and deceivers, specially they of the circumcision: Whose mouths must be stopped, who subvert whole houses, teaching things which they ought not, for filthy lucre’s sake.

Then said the king, The one saith, This is my son that liveth, and thy son is the dead: and the other saith, Nay; but thy son is the dead, and my son is the living. And the king said, Bring me a sword. And they brought a sword before the king. And the king said, Divide the living child in two, and give half to the one, and half to the other. Then spake the woman whose the living child was unto the king, for her bowels yearned upon her son, and she said, O my lord, give her the living child, and in no wise slay it. But the other said, Let it be neither mine nor thine, but divide it. Then the king answered and said, Give her the living child, and in no wise slay it: she is the mother thereof. And all Israel heard of the judgment which the king had judged; and they feared the king: for they saw that the wisdom of God was in him, to do judgment.

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.
