Ha'azinu: Chapter 5
Moses revealed on the day he passed away

Rabbi Shimon says that the last generation that left Egypt knew everything, because Moses revealed it all to them during the forty years that they wandered in the wilderness. Rabbi Yitzchak had taught that even Moses only revealed secrets on the last day before he died, once he was given permission to reveal them. The poem that Moses delivered to the people was drawn from the Holy Spirit downwards, and he called on the name of God when he spoke.
