יוֹר֤וּ מִשְׁפָּטֶ֙יךָ֙ לְיַעֲקֹ֔ב וְתוֹרָתְךָ֖ לְיִשְׂרָאֵ֑ל יָשִׂ֤ימוּ קְטוֹרָה֙ בְּאַפֶּ֔ךָ וְכָלִ֖יל עַֽל־מִזְבְּחֶֽךָ׃
Insegneranno a Giacobbe le tue ordinanze e Israele la tua legge; Metteranno l'incenso davanti a te e tutto l'olocausto sul tuo altare. .
Rashi on Deuteronomy
יורו משפטיך THEY MAY TEACH THY JUDGMENTS (the emphasis is to be placed on “they”) — they alone are worthy of doing this (cf. Onkelos).
Sforno on Deuteronomy
יורו משפטיך ליעקב, Moses prays to G’d that seeing that this tribe has proven so fit as a standard bearer of the Jewish nation, let them be the teachers of Torah. Compare Moed Katan 17 “if the Rabbi is comparable to an angel, let the people come and listen to his words of Torah.”
Kitzur Baal HaTurim on Deuteronomy
They will spread throughout the Jewish people to learn Torah. Yaakov also said, “I will spread them in Yisroel.”
