Kabbalah su Esodo 33:20

Jacob arrived at the prophecy of "and...lived" only in Egypt. It was an excellent prophecy, the like of which was never prophesied before. None of the prophets was worthy of it except for him and Moses. It is written of Moses, "For no man shall see Me, and live" (Shemot 33:20). Of Jacob, it is written, "And Jacob lived", the prophecy which descends from the shining mirror.

Another explanation of, "And Hashem appeared to him by the terebinths of Mamre." The Sages began with this verse that speaks of the time of one's demise. We learned that Rabbi Yehuda said that at the time of a person's death, which is the day of the Great Judgment when the soul is separated from the body, no one leaves the world before he sees the Shechinah, as it is written, "...for no man shall see me and live" (Ex. 33: 20). And three ministering angels accompany the Shechinah to welcome the soul of the righteous, as it is written, "And Hashem appeared to him...in the heat of the day." This is the Day of Judgment that burns like a furnace in order to separate the soul from the body.

Rabbi Abba opened the discussion, saying: "And Manoach said to his wife, We shall surely die, because we have seen Elohim" (Judges 13:22). Even though Manoach was not aware of his actions, he still said, it is written, "For man shall not see Me and live" (Ex. 33:20). We have certainly seen Him, and therefore we shall certainly die. Yet, we who have seen and have had the privilege of seeing that light that accompanied us shall stay alive, because the Holy One, blessed be He, sent him to us, to teach us the secrets of the Wisdom that he chose to reveal . How happy is our lot!
