Ecclesiastes 10:12

Let your speech be alway with grace, seasoned with salt, that ye may know how ye ought to answer every man.

And all bare him witness, and wondered at the gracious words which proceeded out of his mouth. And they said, Is not this Joseph’s son?

He that loveth pureness of heart, for the grace of his lips the king shall be his friend.

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

Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.

But I would strengthen you with my mouth, and the moving of my lips should asswage your grief.

A false witness shall not be unpunished, and he that speaketh lies shall not escape.

So they shall make their own tongue to fall upon themselves: all that see them shall flee away.

He that winketh with the eye causeth sorrow: but a prating fool shall fall.

As a thorn goeth up into the hand of a drunkard, so is a parable in the mouth of fools.

And he saith unto him, Out of thine own mouth will I judge thee, thou wicked servant. Thou knewest that I was an austere man, taking up that I laid not down, and reaping that I did not sow:

She openeth her mouth with wisdom; and in her tongue is the law of kindness.

The mouth of the righteous speaketh wisdom, and his tongue talketh of judgment.

The wise in heart will receive commandments: but a prating fool shall fall.

As for the head of those that compass me about, let the mischief of their own lips cover them.

There is that speaketh like the piercings of a sword: but the tongue of the wise is health.

A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things.

A man hath joy by the answer of his mouth: and a word spoken in due season, how good is it!

And David said unto him, Thy blood be upon thy head; for thy mouth hath testified against thee, saying, I have slain the LORD’s anointed.
