וַיֹּ֨אמֶר יְהוָ֜ה אֶל־מֹשֶׁ֗ה דַּבֵּר֮ אֶל־אַהֲרֹ֣ן אָחִיךָ֒ וְאַל־יָבֹ֤א בְכָל־עֵת֙ אֶל־הַקֹּ֔דֶשׁ מִבֵּ֖ית לַפָּרֹ֑כֶת אֶל־פְּנֵ֨י הַכַּפֹּ֜רֶת אֲשֶׁ֤ר עַל־הָאָרֹן֙ וְלֹ֣א יָמ֔וּת כִּ֚י בֶּֽעָנָ֔ן אֵרָאֶ֖ה עַל־הַכַּפֹּֽרֶת׃
et il dit à Moïse: "Signifie à Aaron, ton frère, qu’Il ne peut entrer à toute heure dans le sanctuaire, dans l’enceinte du voile, devant le propitiatoire qui est sur l’arche, s’il ne veut encourir la mort; car je me manifeste, dans un nuage, au-dessus du propitiatoire.
Noam Elimelekh
Speak to Aharon your brother - we see to explain that [here] the Holy Torah is teaching people who rebuke others that they should not rebuke those who are clowns and empty-headed, into whom clearly the words [of rebuke] will not enter into their ears at all, as it is said "do not rebuke a scoffer" (Prov. 9:8); only people who pay attention to the voice of rebuke and mussar and who want to do teshuvah, to those one speak and directs to the ways of teshuvah.
