בְּרֹ֣ב דְּ֭בָרִים לֹ֣א יֶחְדַּל־פָּ֑שַׁע וְחֹשֵׂ֖ךְ שְׂפָתָ֣יו מַשְׂכִּֽיל׃
말이 많으면 허물을 면키 어려우나 그 입술을 제어하는 자는 지혜가 있느니라
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.”
