[If a person was brought by the waiter wine and perfumed oil at the end of the meal,] Bet Shammai say, “He should hold the cup of wine in his right hand and perfumed oil in his left hand. [Then] he should say the Beracha (blessing) on the wine, and after that [he should make the Beracha] on the oil.” And Bet Hillel say, “He should hold the perfumed oil in his right hand and the cup of wine in his left hand. [Then] he should say a Beracha on the oil and smear it onto the head of the waiter, [if the waiter was in fact an Am Haaretz (a person uneducated in Torah law). However,] if the waiter was a Talmid Chacham (Torah Scholar) [then] he should smear it onto the wall, because it is not praiseworthy for a Talmid Chacham to go out perfumed.”

Adonoy return us. Because he concludes with words of reproof, he had to repeat the preceding verse again,¹⁴In order to end on a note of consolation. and so did Yeshayahu, Trei Osor, and Koheles.
