Kabbalah su Genesi 7:12

Rabbi Yosi said that the instant the Holy One blessed be He, resurrects the dead, all troubles will end, on the fortieth year (after the gathering of the exiles). It has been resolved by law "Forty stripes he may give him, and not exceed" (Devarim 25:3). The journey of Yisrael in the desert (was finished) in the fortieth year. Forty years before the body is resurrected, the soul awaits it in the land of Yisrael. In the fortieth year, the bodies will rise from the dust. After forty days the rain stopped, this is the meaning of the verses "And the rain was upon the earth forty days and forty nights" (Gen. 7:12), and "it came to pass at the end of forty days, that Noah opened" (Gen. 8:6). Also, the time of the Redemption of Yisrael is during the fortieth year. During the fiftieth year, the world, which is Jubilee, will be populated. The return of the soul to the body occurs after forty years of waiting in the land of Yisrael. This is the meaning of, "and Isaac was forty years old." That is, he was waiting for the body. "When he took Rivkah," who was put in the body prepared for him. Their passion and longing at that moment was for the splendor of the Shechinah only and to nourish of Her splendor. This is the meaning of the verse, "Let him kiss me with the kisses of his mouth." Rabbi Abba said, "Let him kiss me" means let him nourish me. Their sole nourishment is the enjoyment and sustenance of the supernal splendor. Rabbi Yosi said that this is proven by the end of the verse, which reads, "for your love is better than wine" (Shir Hashirim 1:2).
