מַעְיָ֣ן נִ֭רְפָּשׂ וּמָק֣וֹר מָשְׁחָ֑ת צַ֝דִּ֗יק מָ֣ט לִפְנֵֽי־רָשָֽׁע׃
義人在惡人面前屈服退讓，就像被踐踏而變得渾濁的泉水，又像被毀壞的水源。
Rashi
A righteous man slipping before a wicked man When a righteous man slips before a wicked man and is afraid to reprove him for his way to his face, the matter is hateful like a muddied spring and a ruined fountain.
