רַבָּן גַּמְלִיאֵל הָיָה אוֹמֵר: כָּל שֶׁלֹּא אָמַר שְׁלשָׁה דְּבָרִים אֵלּוּ בַּפֶּסַח, לא יָצָא יְדֵי חוֹבָתוֹ, וְאֵלּוּ הֵן: פֶּסַח, מַצָּה, וּמָרוֹר.

Rabban Gamliel was accustomed to say, Anyone who has not said these three things on Pesach has not fulfilled his obligation, and these are them: the Pesach sacrifice, matsa and marror.

פֶּסַח שֶׁהָיוּ אֲבוֹתֵינוּ אוֹכְלִים בִּזְמַן שֶׁבֵּית הַמִּקְדָּשׁ הָיָה קַיָּם, עַל שׁוּם מָה? עַל שׁוּם שֶׁפָּסַח הַקָּדוֹשׁ בָּרוּךְ הוּא עַל בָּתֵּי אֲבוֹתֵינוּ בְּמִצְרַיִם, שֶׁנֶּאֱמַר: וַאֲמַרְתֶּם זֶבַח פֶּסַח הוּא לַיי, אֲשֶׁר פָּסַח עַל בָּתֵּי בְנֵי יִשְׂרָאֵל בְּמִצְרַיִם בְּנָגְפּוֹ אֶת־מִצְרַיִם, וְאֶת־בָּתֵּינוּ הִצִּיל וַיִּקֹּד הָעָם וַיִּשְׁתַּחווּ.

The Pesach [passover] sacrifice that our ancestors were accustomed to eating when the Temple existed, for the sake of what [was it]? For the sake [to commemorate] that the Holy One, blessed be He, passed over the homes of our ancestors in Egypt, as it is stated (Exodus 12:27); "And you shall say: 'It is the passover sacrifice to the Lord, for that He passed over the homes of the Children of Israel in Egypt, when He smote the Egyptians, and our homes he saved.’ And the people bowed the head and bowed."

אוחז המצה בידו ומראה אותה למסובין:

He holds the matsa in his hand and shows it to the others there.

מַצָּה זוֹ שֶׁאָנוֹ אוֹכְלִים, עַל שׁוּם מַה? עַל שׁוּם שֶׁלֹּא הִסְפִּיק בְּצֵקָם שֶׁל אֲבוֹתֵינוּ לְהַחֲמִיץ עַד שֶׁנִּגְלָה עֲלֵיהֶם מֶלֶךְ מַלְכֵי הַמְּלָכִים, הַקָּדוֹשׁ בָּרוּךְ הוּא, וּגְאָלָם, שֶׁנֶּאֱמַר: וַיֹּאפוּ אֶת־הַבָּצֵק אֲשֶׁר הוֹצִיאוּ מִמִּצְרַיִם עֻגֹת מַצּוֹּת, כִּי לֹא חָמֵץ, כִּי גֹרְשׁוּ מִמִּצְרַיִם וְלֹא יָכְלוּ לְהִתְמַהְמֵהַּ, וְגַם צֵדָה לֹא עָשׂוּ לָהֶם.

This matsa that we are eating, for the sake of what [is it]? For the sake [to commemorate] that our ancestors' dough was not yet able to rise, before the King of the kings of kings, the Holy One, blessed be He, revealed [Himself] to them and redeemed them, as it is stated (Exodus 12:39); "And they baked the dough which they brought out of Egypt into matsa cakes, since it did not rise; because they were expelled from Egypt, and could not tarry, neither had they made for themselves provisions."

אוחז המרור בידו ומראה אותו למסובין:

He holds the marror in his hand and shows it to the others there.

מָרוֹר זֶה שֶׁאָנוּ אוֹכְלִים, עַל שׁוּם מַה? עַל שׁוּם שֶׁמֵּרְרוּ הַמִּצְרִים אֶת־חַיֵּי אֲבוֹתֵינוּ בְּמִצְרַיִם, שֶׁנֶּאֱמַר: וַיְמָרְרוּ אֶת חַיֵּיהם בַּעֲבֹדָה קָשָה, בְּחֹמֶר וּבִלְבֵנִים וּבְכָל־עֲבֹדָה בַּשָּׂדֶה אֶת כָּל עֲבֹדָתָם אֲשֶׁר עָבְדוּ בָהֶם בְּפָרֶךְ.

This marror [bitter greens] that we are eating, for the sake of what [is it]? For the sake [to commemorate] that the Egyptians embittered the lives of our ancestors in Egypt, as it is stated (Exodus 1:14); "And they made their lives bitter with hard service, in mortar and in brick, and in all manner of service in the field; in all their service, wherein they made them serve with rigor."
