………a fool’s voice is known by his many words. Ecclesiastes 5:3
The words of a wise man’s mouth are gracious, But the lips of a fool shall swallow him up; Ecclesiastes 10:12
The entrance of Your words gives light; It gives the understanding to the simple. Psalm 119:130
The words of his mouth begin with foolishness, And the end of his talk is raving madness. Ecclesiastes 10:13
A fool also multiplies words. Ecclesiastes 10:14
……….they sit before you as My people, and they hear your words, but they do not do them; for with their mouth they show much love, but their hearts pursue their own gain. Ezekiel 33:31
Words do matter and God knows if we really mean what we are saying; He knows our thoughts, He knows our hearts. It would also seem that positive , kind and uplifting words has a lot to do with our health and well being.
