Avot5: 18
כָּל הַמְזַכֶּה אֶת הָרַבִּים — אֵין חֵטְא בָּא עַל יָדוֹ. וְכָל הַמַּחֲטִיא אֶת הָרַבִּים — אֵין מַסְפִּיקִין בְּיָדוֹ לַעֲשׂוֹת תְּשׁוּבָה. משֶׁה זָכָה וְזִכָּה אֶת הָרַבִּים — זְכוּת הָרַבִּים תָּלוּי בּוֹ, שֶׁנֶּאֱמַר: ”צִדְקַת ה' עָשָׂה וּמִשְׁפָּטָיו עִם־יִשְׂרָאֵל”. יָרָבְעָם חָטָא וְהֶחֱטִיא אֶת הָרַבִּים — חֵטְא הָרַבִּים תָּלוּי בּוֹ, שֶׁנֶּאֱמַר: ”עַל־חַטֹּאות יָרָבְעָם [בֶּן נְבָט] אֲשֶׁר חָטָא וַאֲשֶׁר הֶחֱטִיא אֶת־יִשְׂרָאֵל”.
Whoever causes the public to do good will not be given the opportunity to sin. But whoever causes the public to do evil will not be given the opportunity to repent. Moses merited and brought merit to the public; [thus] the merit of the public is to his cred-it, as it is said: He carried out the righteousness of Hashem and His ordinances with Israel. Jeroboam son of Nevat sinned and caused the public to sin, [so therefore] the sin of the public is charged against him, as it is said: For the sins of Jeroboam that he committed and that he caused Israel to commit.
