He that goeth about as a talebearer revealeth secrets. Almost the same proverb occurs in Proverbs 11:13, The gadding gossiper is sure to let out any secret entrusted to him; therefore, it is implied, be careful in what you say to him.
Meddle not with him that flattereth with his lips; rather, that openeth wide his lips—that cannot keep his mouth shut, a babbler, as Proverbs 13:3 (where see note). The Vulgate erroneously makes one sentence of the verse, "With him who reveals secrets, and walketh deceitfully, and openeth wide his lips, have no dealings."
Talmud, "When I utter a word, it hath dominion over me; but when I utter it not, I have dominion over it." Says the Persian poet, "The silent man hath his shoulders covered with the garment of security."
Xenocrates used to say that he sometimes was "sorry for having spoken, never for having kept silence" (Cahen).
