“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.
Israel Lovesick for God in the Daughters of Jerusalem
Shir HaShirim Rabbah 8:1
