Psalms

A good man out of the good treasure of his heart bringeth forth that which is good; and an evil man out of the evil treasure of his heart bringeth forth that which is evil: for of the abundance of the heart his 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.

Even so the tongue is a little member, and boasteth great things. Behold, how great a matter a little fire kindleth!

Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.

Then said they, Come, and let us devise devices against Jeremiah; for the law shall not perish from the priest, nor counsel from the wise, nor the word from the prophet. Come, and let us smite him with the tongue, and let us not give heed to any of his words.
