Ecclesiastes 10:12-14. The words of a wise man’s mouth are gracious; but a fool is swallowed by his own lips. The beginning of the words of his mouth is foolishness; and the end of his talk is mischievous madness. A fool also multiplies words.
Galatians 3:2-3. Did you receive the Spirit by the works of the law, or by hearing of faith? Are you so foolish? Having begun in the Spirit, are you now completed in the flesh?
