The Book of Proverbs instructs us concerning the proper use or abuse of our tongue.
Pro. 10:11-13a – The mouth of the righteous is a well of life. But the mouth of the wicked conceals violence. Hatred stirs up strife, but love covers all sins. Wisdom is found on the lips of him who has understanding
Pro. 10:18-19, 20a & 21a – Whoever hides hatred has lying lips, and whoever spreads slander is a fool.
In the multitude of words, sin is not lacking, but he who restrains his tongue is wise.
The tongue of the wise is like choice silver. The lips of the righteous feed & guide many.
Pro. 11:13 – A talebearer reveals secrets, but he who is of a faithful spirit conceals a matter.
Pro. 12:13 & 18-19 – The wicked is ensnared by the transgression of his lips. But the righteous will come through (and out of) trouble.
There is one who speaks like the piercing of a sword, but the tongue of the wise promotes health, bringing healing. The truthful lip shall be established forever, but a lying tongue is but for a moment.
Pro. 15:1-2a, 4 & 23 – A soft answer turns away wrath, but a harsh word stirs up anger. The tongue of the wise uses knowledge properly. A gentle, wholesome tongue (with its healing power) is a tree of life, but perverseness in it breaks the spirit. A man has joy by the answer of his mouth, and a word spoken in due season (at the right moment), how good it is!
Pro. 16:23-24 & 32 – The heart of the wise teaches his mouth, and adds learning to his lips. Pleasant words are like a honeycomb, sweet to the soul and health to the bones. He who is slow to anger is better than the mighty, and he who rules his own spiritthan he who takes a city.
Pro. 17:14 & 27-28 – The beginning of strife is like when water first trickles (from a crack in a dam); therefore stop contention before it becomes worse and a quarrel starts.
He who has knowledge spares his words, and a man of understanding is of a calm spirit. Even a fool is counted wise when he holds his peace; when he keep his mouth shut he is considered perceptive, a man of understanding.
Pro. 18:7 – A fool’s mouth is his destruction, and his lips are the snare of his soul.
Pro. 25:11-12 – A word fitly spoken (the right words at the right time) is like apples of gold in settings of silver. Like an earring or ornament of fine gold, is a wise reproof to a listening and obedient ear.
