잠언 17:28의 탈무드

R. Ḥiyya taught: Silence is good for the wise and how much more so for fools; and so did Solomon say, Even a fool, when he holdeth his peace, is counted wise.¹⁷Prov. 17, 28. It is not necessary to say, ‘When a wise man holdeth his peace’.¹⁸Because a wise man knows when to be silent.

Bar Qappara stated: Silence behoves the Sages, and so much more the fools. And also Solomon says¹³⁵Prov. 17:28., also a silent dolt is considered to be wise, and it is not necessary to say, a silent sage¹³⁶Since the only uncomplicated case in the Mishnaiot is when nobody says anything. Babli 99a..

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.”
