"Let the words of my mouth and the meditation of my heart be acceptable in Your sight, O Lord, my rock and my Redeemer."
"Let no unwholesome word proceed from your mouth, but only such a word as is good for edification according to the need of the moment, so that it will give grace to those who hear."
"The one who guards his mouth preserves his life; the one who opens wide his lips comes to ruin."
"Like the Holy One who called you, be holy yourselves also in all your behavior."
1 Peter 1:15
"He who restrains his words has knowledge, and he who has a cool spirit is a man of understanding. Even a fool, when he keeps silent, is considered wise; when he closes his lips, he is considered prudent."
"The good man out of the good treasure of his heart brings forth what is good; and the evil man out of the evil treasure brings forth what is evil; for his mouth speaks from that which fills his heart."
"The tongue of the wise makes knowledge acceptable, but the mouth of fools spouts folly."
"A man has joy in an apt answer, and how delightful is a timely word!"
tongue is a small part of the body, and yet it boasts of great things. See how
great a forest is set aflame by such a small fire! And the tongue is a fire,
the very world of iniquity; the tongue is set among our members as that which
defiles the entire body, and sets on fire the course of our life, and is set on
fire by hell.
"For every species of beasts and birds, of reptiles and creatures of the sea, is tamed and has been tamed by the human race. But no one can tame the tongue; it is a restless evil and full of deadly poison. With it we bless our Lord and Father, and with it we curse men, who have been made in the likeness of God; from the same mouth come both blessing and cursing."
"Do not be a witness against your neighbor without cause, and do not deceive with your lips."
"A fool's mouth is his ruin, and his lips are the snare of his soul."
"The one who desires life, to love and see good days, must keep his tongue from evil and his lips from speaking deceit."
1 Peter 3:10
"The words of a man's mouth are deep waters; the fountain of wisdom is a bubbling brook."
