Song of Songs Rabbah 7:10

¹“Your palate is like fine wine that goes pleasantly for my beloved, moving the lips of the sleeping” (Song of Songs 7:10). “Your palate is like fine wine.” Rabbi Yoḥanan said: At that moment, the Holy One blessed be He called the ministering angels, all of them, and He said to them: ‘Go down and kiss the lips of the ancestors of these; just as they took action before Me in fire, 38:13) and Isaac was willingly bound on the altar, where he thought he would be slaughtered and burned. so too, their descendants took action before Me in fire.’ Rabbi Azarya [said] in the name of Rabbi Yehuda ben Rabbi Simon: At that moment, the Holy One blessed be He called the ministering angels and said to them: ‘Go down and kiss their lips, for had they not accepted My Torah and My dominion at Sinai, I would have become the enemy of those who sleep in the Cave of Makhpela.’ “Moving the lips of the sleeping,” Rabbi Yoḥanan ben Toreta said: Even though one is dead, his lips move for him in the grave. What is the source? “Moving the lips of the sleeping.” Shmuel said: It is like a basket of grapes whose liquid flows on its own. Rabbi Ḥanina bar Pappa and Rabbi Simon, one said: Like one who drinks spiced wine, and one said: Like one who drinks aged wine. Even though he drank it already, its taste and its fragrance remains in his mouth.
