One who says the Shema must remember the exodus from Egypt when saying "Emet V'Yatziv". Rabbi [Yehuda] says that one must remember the [Davidic] kingship. Aherim say that one must remember the slaying of the first born and the dividing of the Red Sea.

Rabbi Elazar ben Azariah said, "Behold I am like a man of seventy years and I have not merited [to understand why] the exodus from Egypt should be said at night until Ben Zoma explicated it, as it is stated (Deuteronomy 16:3), 'In order that you remember the day of your going out from the land of Egypt all the days of your life;' 'the days of your life' [indicates that the remembrance be invoked during] the days, 'all the days of your life' [indicates that the remembrance be invoked also during] the nights." But the Sages say, "'the days of your life' [indicates that the remembrance be invoked in] this world, 'all the days of your life' [indicates that the remembrance be invoked also] in the days of the Messiah."
