||[You will thus be able] to distinguish between the holy and the common, and between the ritually unclean and the clean.
Ulehavdil beyn hakodesh uveyn hachol uveyn hatame uveyn hatahor.
||[You will also be able] to render decisions for the Israelites in all the laws that God has taught you through Moses.
Ulehorot et-beney Yisra'el et kol-hachukim asher diber Adonay aleyhem beyad-Moshe.
|You will thus be able|
(Saadia). Or, 'This is to' (Rashi).
|to render decisions|
This teaches that a rabbi may not render decisions when drunk (Kerithoth 13b; Yad, Biyath HaMikdash 1:3). According to some, this also implies a positive commandment for a duly qualified rabbi to render decisions in Torah law (Sefer Mitzvoth Katan 111; Cheredim, Positive 4:20).
