"Put away perversity from your mouth; keep corrupt talk far from your lips."
"Reckless words pierce like a sword, but he tongue of the wise brings healing. Truthful lips endure forever, but a lying tongue lasts only a moment...The Lord detests lying lips but he delights in men who are truthful."
–Proverbs 18, 19, 22
"Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen."
"An anxious heart weighs a man down, but a kind word cheers him up."
"Out of the overflow of the heart the mouth speaks."
"A gentle answer turns away wrath, but a harsh word stirs up anger. The tongue of the wise commends knowledge, but the mouth of the fool gushes folly...The tongue that brings healing is a tree of life, but a deceitful tongue crushes the spirit."
–Proverbs 15:1, 2, 4
"A man finds joy in giving an apt reply - and how good is a timely word!"
"A wise man's heart guides his mouth, and his lips promote instruction. Pleasant words are a honeycomb, sweet to the soul and healing to the bones."
