We mention the Exodus from Egypt at night. R’ Elazar ben Azaryah said: Behold, I am like a seventy-year-old man, yet I did not prevail [with my argument] that the Exodus from Egypt should be mentioned at night, until this was expounded by Ben Zoma: For it is stated: So that you will remember the day of your departure from the land of Egypt all the days of your life (Deuteronomy 16:3.). The days of your life — [this means] the days; all the days of your life — [this includes] the nights [also]. But the Sages say: The days of your life — [this means] this world; all the days of your life — [this comes] to include the days of the Messiah.
