Matthew 15:18

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

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

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

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

"The lips of the righteous know what is acceptable: but the mouth of the wicked speaketh frowardness."

"A naughty person, a wicked man, walketh with a froward mouth."

"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:"

"As saith the proverb of the ancients, Wickedness proceedeth from the wicked: but mine hand shall not be upon thee."

"The words of his mouth are iniquity and deceit: he hath left off to be wise, and to do good."
