Mga Sanggunian sa Talmud para sa Genesis 45:27: Avot DeRabbi Natan

Rabbi Shimon would say: Such is the punishment for a liar, that even when he speaks the truth, no one listens to him. So we find with the children of Jacob, who deceived their father. In the beginning he believed them, as it says (Genesis 37:31), “They took Joseph’s coat, slaughtered a goat,” and then it says (Genesis 37:33), “He recognized it, and said: This is my son’s coat! But afterward, even when they spoke the truth to him, he did not believe them, as it says (Genesis 45:26), ([“His heart became numb, for he did not believe them.”]) “They told him, and said: Joseph is still alive…[but] he did not believe them.”
Some say that the holy spirit that had departed from Jacob now returned to him, as it says (Genesis 45:27), “And the spirit of their father Jacob was revived.”
