신명기 33:10 해설: Rashi, Chizkuni, Ibn Ezra & Sforno

יורו משפטיך THEY MAY TEACH THY JUDGMENTS (the emphasis is to be placed on “they”) — they alone are worthy of doing this (cf. Onkelos).

יורו משפטיך ליעקב, “They will teach Your ordinances to Yaakov;” seeing that they are impartial people not showing undue favours to anyone, they are qualified to teach and help enforce Your laws. (Compare Ezekiel 44,23: ואת עמי יורו,”and My people they will instruct.) It is also written in Deut: 17,9: ובאת אל הכהנים הלוים והגידו לך את דבר המשפט, “when you will come to the priests, who are members of the tribe of the Levites, and they will tell you matters concerning the ordinances.”An alternate interpretation: “they will teach you the laws of the Torah, since they do not have to earn their living from farming, etc., they have the time to study and teach all these laws.” The reason they did not receive any share of the land of Israel was to enable them to do just that.

they shall place incense i.e., the kohanim among them.

וכליל — means burnt-offering (which was entirely (כליל) burnt on the altar) (Sifrei Devarim 351:3).
