מַזְכִּירִין יְצִיאַת מִצְרַיִם בַּלֵּילוֹת. אָמַר רַבִּי אֶלְעָזָר בֶּן עֲזַרְיָה, הֲרֵי אֲנִי כְּבֶן שִׁבְעִים שָׁנָה, וְלֹא זָכִיתִי שֶׁתֵּאָמֵר יְצִיאַת מִצְרַיִם בַּלֵּילוֹת, עַד שֶׁדְּרָשָׁהּ בֶּן זוֹמָא, שֶׁנֶּאֱמַר (דברים טז) לְמַעַן תִּזְכֹּר אֶת יוֹם צֵאתְךָ מֵאֶרֶץ מִצְרַיִם כֹּל יְמֵי חַיֶּיךָ. יְמֵי חַיֶּיךָ, הַיָּמִים. כֹּל יְמֵי חַיֶּיךָ, הַלֵּילוֹת. וַחֲכָמִים אוֹמְרִים, יְמֵי חַיֶּיךָ, הָעוֹלָם הַזֶּה. כֹּל יְמֵי חַיֶּיךָ, לְהָבִיא לִימוֹת הַמָּשִׁיחַ:
Tosefta Berakhot
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.
Pesach Haggadah
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."
