Ecclesiastes 10:12-14

¹²The words of a wise man's mouth bring grace; but the lips of a fool will destroy himself.

¹³The beginning of the words of his mouth is foolishness; and the last that cometh out of his mouth is evil-bringing madness.

¹⁴The fool also multiplieth words; but a man cannot know what is to be; and what is to be after him, who can tell him?
