וְקָרַבְתִּ֣י אֲלֵיכֶם֮ לַמִּשְׁפָּט֒ וְהָיִ֣יתִי ׀ עֵ֣ד מְמַהֵ֗ר בַּֽמְכַשְּׁפִים֙ וּבַמְנָ֣אֲפִ֔ים וּבַנִּשְׁבָּעִ֖ים לַשָּׁ֑קֶר וּבְעֹשְׁקֵ֣י שְׂכַר־שָׂ֠כִיר אַלְמָנָ֨ה וְיָת֤וֹם וּמַטֵּי־גֵר֙ וְלֹ֣א יְרֵא֔וּנִי אָמַ֖ר יְהוָ֥ה צְבָאֽוֹת׃
내가 심판하러 너희에게 임할 것이라 술수하는 자에게와 간음하는 자에게와 거짓 맹세하는 자에게와 품꾼의 삯에 대하여 억울케 하며 과부와 고아를 압제하며 나그네를 억울케 하며 나를 경외치 아니하는 자들에게 속히 증거하리라 만군의 여호와가 말하였느니라
Mesilat Yesharim
In the chapter "All are Liable" (Chagiga 5a): "When Rabbi Yochanan would come to this verse, he would weep - 'I will come near you to judgment and I will be a swift witness...' (Malachi 3:5) - a servant whose minor offenses are weighed just like major offenses, is there any remedy for him?
