וְחִכֵּ֕ךְ כְּיֵ֥ין הַטּ֛וֹב הוֹלֵ֥ךְ לְדוֹדִ֖י לְמֵישָׁרִ֑ים דּוֹבֵ֖ב שִׂפְתֵ֥י יְשֵׁנִֽים׃
네 입은 좋은 포도주 같을 것이니라 이 포도주는 나의 사랑하는 자를 위하여 미끄럽게 흘러 내려서 자는 자의 입으로 움직이게 하느니라
Rashi
And let your speech be like good wine. Be cautious with your answers that they should be like the best wine.29See Daniyeil, chapter 3.
Ezra ben Solomon
And your mouth is like the choicest wine: Your words are nothing less than an advocate, championing the cause of Israel before the Glory, giving expression to the lips of the sleepers—these are Israel in their exile.
Rashi
It flows for my beloved in sincerity. I am careful to answer them that I will remain steadfast in my faith, and my speech will go before my Beloved with sincere love, which comes from the heart, and not with deceit and guile.
Rashi
Like good wine. Which makes the lips of the sleeping murmur. Even my ancestors in the grave will rejoice with me and give thanks for their lot.30I.e., your answers should be clear and potent. “דּוֹבֵב” [means] causing to move, fromier in O.F. and its root, is an expression of speech. And this is the answer, “I am my Beloved’s and He longs for me.”31The comparison to wine is because the taste of wine remains in one’s mouth long after drinking it. The mere mention of the words of the departed sages, causes their lips to murmur in their graves. See Maseches Yevamos 97a and Rashi there.
