אַל־תִּ֭תְאָו לְמַטְעַמּוֹתָ֑יו וְ֝ה֗וּא לֶ֣חֶם כְּזָבִֽים׃
Ne convoite pas ses plats fins, car c’est une nourriture trompeuse.
Rashi on Proverbs
Do not desire his delicacies but leave him and go [to study] before a competent teacher, and do not embarrass him with questions, since he does not know what to answer.
