Matthew 12:35

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

The heart of the righteous studieth to answer: but the mouth of the wicked poureth out evil things.

A wholesome tongue is a tree of life: but perverseness therein is a breach in the spirit.

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

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

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

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.

The tongue of the just is as choice silver: the heart of the wicked is little worth. The lips of the righteous feed many: but fools die for want of wisdom.

The wise in heart shall be called prudent: and the sweetness of the lips increaseth learning. Understanding is a wellspring of life unto him that hath it: but the instruction of fools is folly. The heart of the wise teacheth his mouth, and addeth learning to his lips.

The words of the wicked are to lie in wait for blood: but the mouth of the upright shall deliver them.

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

The mouth of the righteous speaketh wisdom, and his tongue talketh of judgment. The law of his God is in his heart; none of his steps shall slide.

He that speaketh truth sheweth forth righteousness: but a false witness deceit. There is that speaketh like the piercings of a sword: but the tongue of the wise is health. The lip of truth shall be established for ever: but a lying tongue is but for a moment.

Then said he unto them, Therefore every scribe which is instructed unto the kingdom of heaven is like unto a man that is an householder, which bringeth forth out of his treasure things new and old.
