כֹּ֣פֶר לַצַּדִּ֣יק רָשָׁ֑ע וְתַ֖חַת יְשָׁרִ֣ים בּוֹגֵֽד׃
악인은 의인의 대속이 되고 궤사한 자는 정직한 자의 대신이 되느니라
Rashi on Proverbs
A wicked man shall be ransom for a righteous man, and a treacherous one instead of the upright A righteous man is rescued, and a wicked man comes in his stead (above 11:8), such as Mordecai and Haman.
