Song of Songs Rabbah 5:6

¹“I opened for my beloved, but my beloved had slipped away and gone. My soul departed when he spoke. I sought him, but did not find him; I called him, but he did not answer me” (Song of Songs 5:6). “I opened for my beloved, but my beloved had slipped away and gone [ avar ]” – He was appeased, and then He became filled with wrath [ evra ] toward me. “My soul departed when he spoke” – upon the speech of Cyrus who decreed: Whoever has not crossed the Euphrates shall not cross. “I sought him, but did not find him; I called him, but he did not answer me.” Another matter: “I opened for my beloved, but my beloved had slipped away and gone” – He was appeased, and then He became filled with wrath [ evra ] toward me like a pregnant [ uberet ] woman. My soul departed when he spoke” – with His speech, from the sound of His first commandment, when He said: “I am the Lord your God” (Exodus 20:2). “I sought him, but did not find him; I called him, but he did not answer me.”
