Shir HaShirim Rabbah 5:8/שיר השירים רבה ה׳:ח׳

1“I administer an oath to you, daughters of Jerusalem; if you find my beloved, what shall you tell him? That I am lovesick” (Song of Songs 5:8).“I administer an oath to you, daughters of Jerusalem…what shall you tell him? That I am lovesick” – just as the ill person yearns for healing, so, the generation that was in Egypt yearned for redemption.
