창세기 45:27의 미드라쉬

It was because of this episode that a famine befell Canaan, compelling Joseph’s ten brothers to descend to Egypt to buy grain, where they discovered that Joseph was still alive. (Only then) did they abrogate the pact of excommunication and Jacob learned that Joseph was alive. It is written about him: The spirit of Jacob their father revived (Gen. 45:27). Had his spirit actually died? No! His spirit was revived from the despair that resulted from the vow of excommunication they had entered into, and the Holy Spirit had departed from him because of it, but now it hovered over him once again.

Rabbi Jannai said: The sale of Joseph was not atoned by the tribes until they died, as it is said, "And the Lord of hosts revealed Himself in mine ears, Surely this iniquity shall not be purged from you till ye die" (Isa. 22:14). Owing to the sale (of Joseph) a famine came into the land of Israel for seven years, and the brethren of Joseph "went down to buy corn" (Gen. 42:3) in Egypt. And they found Joseph (still) living, and they absolved themselves of the ban; and Jacob heard about Joseph that he was living, and his soul and his spirit revived. Did their father Jacob's spirit die, so that it had to be revived? But, owing to the ban, the Holy Spirit had departed from him, and when they had removed the ban the Holy Spirit rested on him as at first; that || is what is written, "The spirit of Jacob their father revived" (Gen. 45:27).
