1. "Give ear, O heavens, and I will speak; and hear, O earth, the words of my mouth" (Devarim 32:1). Rabbi Yehuda opened with, "I opened to my beloved; but my beloved had turned away, and was gone...I sought him, but I could not find him; I called him, but he gave me no answer" (Shir Hashirim 5:6). Before that it is written, "I sleep, but my heart wakes..." (Ibid. 2). "I sleep," says the Congregation of Yisrael, "I sleep" away from the commandments of the Torah when I traveled the wilderness; "but my heart wakes" to bring them to the land of Yisrael to legislate laws for them. For all the commandments of the Torah are present in the land of Yisrael. "hark, my beloved is knocking" (Ibid.) refers to Moses, who reproved Yisrael with many arguments and quarrels, as it is written, "These are the words..." (Devarim 1:1), "You have been rebellious" (Devarim 9:24), and, "Also in Horeb you provoked..." (Ibid. 8). This is the meaning of, "knocking."
