בְּרֹ֣ב דְּ֭בָרִים לֹ֣א יֶחְדַּל־פָּ֑שַׁע וְחֹשֵׂ֖ךְ שְׂפָתָ֣יו מַשְׂכִּֽיל׃
話語多了，難免有過錯；約束嘴唇的，才是明智人。
Avot DeRabbi Natan
Wisdom does not produce words, and words do not produce wisdom; only action does. Anyone who talks too much brings about sin, as it says (Proverbs 10:19), “When there is too much talking, there is no lack of sin.” And it says (Proverbs 17:28), “Even a fool, if he keeps silent, is deemed wise.”
