In this episode, we examine chapter 90 of Tehillim, which appears in Pesukei D'Zimra for Shabbat and Yom Tov. We discuss the atribution of this chapter to Moshe Rabbeinu, noting that it seems to be a reflection from the conclusion of his life. We also consider how the author of the Mizmor grapples with the transience and impermanence of human life relative to Hashem's eternity, and the role that service of Hashem plays in giving life meaning.
