לְחָיָו֙ כַּעֲרוּגַ֣ת הַבֹּ֔שֶׂם מִגְדְּל֖וֹת מֶרְקָחִ֑ים שִׂפְתוֹתָיו֙ שֽׁוֹשַׁנִּ֔ים נֹטְפ֖וֹת מ֥וֹר עֹבֵֽר׃
Seine Wangen wie ein würziges Beet, wie Türme von Wohlgerüchen, seine Lippen wie Rosen, wie fließende Myrrhe traufelnd.

This is like the verse, (Song of Songs 5.13) "His lips are lilies, dripping with myrrh." Lips are like Pessach, which is [a homonym of] Peh Sach, a speaking mouth; Shoshana, meaning lilies, is Esther (according to the Zohar, and they have equivalent numerical values); "Dripping with myrrh" refers to Mordechai, who is [hinted at in the translation of the verse (Exodus 30:23)Mor Dror, and this ["Dror"] is a synonym of freedom, like the freedom of Pesach.
Noam Elimelekh
And this is [the meaning of] "sweetness drops from your lips, bride, [milk and honey are under your tongue] etc" (Songs 4:11) - also a hint to those three levels. "Sweetness drops" is a hint to the level of awe, [since] "myrrh drops" (Songs 5:13) is explained by our sages z"l with "do not read myrrh but etc" (Shabbat 30b:6). And "your lips bride" is a hint to the level of love, like a bride is beloved by her fiance. And "honey and milk under your tongue" is a hint to the third level, that all one's deeds are like honey and are splendid for all people.
