מלושני [מְלָשְׁנִ֬י] בַסֵּ֨תֶר ׀ רֵעֵהוּ֮ אוֹת֪וֹ אַ֫צְמִ֥ית גְּֽבַהּ־עֵ֭ינַיִם וּרְחַ֣ב לֵבָ֑ב אֹ֝ת֗וֹ לֹ֣א אוּכָֽל׃
Whoso slandereth his neighbour in secret, him will I destroy; Whoso is haughty of eye and proud of heart, him will I not suffer.
Read Jewish philosophical commentary on Psalms 101:5: and classical philosophical sources.
