Ecclesiastes 10:11-14

¹¹If a serpent biteth, it biteth in silence; he that backbiteth privily, hath nothing less than it.

¹²The words of the mouth of a wise man be grace; and the lips of an unwise man shall cast him down.

¹³The beginning of his words is folly; and the last thing of his mouth is the worst error.

¹⁴A fool multiplieth words; a man knoweth not, what was before him, and who may show to him that, that shall come after him?
