Hassidout sur Le Deutéronome 33:10

יוֹר֤וּ מִשְׁפָּטֶ֙יךָ֙ לְיַעֲקֹ֔ב וְתוֹרָתְךָ֖ לְיִשְׂרָאֵ֑ל יָשִׂ֤ימוּ קְטוֹרָה֙ בְּאַפֶּ֔ךָ וְכָלִ֖יל עַֽל־מִזְבְּחֶֽךָ׃

ils enseignent tes lois à Jacob et ta doctrine à Israël; présentent l’encens devant ta face, et l’holocauste sur ton autel.

And this is of the aspect of incense, which connects the heating of the heart with the spirit, and this is (Proverbs 27) Incense will gladden the heart” and this is (Deuteronomy 33) “They will put incense in your brow,” that through the aspect of incense as we have mentioned, the aspect of “By the sweat of your brow you will eat bread” will be nullified.
