Proverbs 10:18-21 King James Version (KJV)
18 He that hideth hatred with lying lips, and he that uttereth a slander, is a fool.
19 In the multitude of words there wanteth not sin: but he that refraineth his lips is wise.
20 The tongue of the just is as choice silver: the heart of the wicked is little worth.
21 The lips of the righteous feed many: but fools die for want of wisdom.
These verses so apply to myself as well as almost everyone I know, although these days it’s often the fingers via social media, e-mail, and the like rather than the tongue, but the effect is the same.
