וְזָכַרְתָּ֗ כִּ֣י עֶ֤בֶד הָיִ֙יתָ֙ בְּאֶ֣רֶץ מִצְרַ֔יִם וַֽיִּפְדְּךָ֖ יְהוָ֣ה אֱלֹהֶ֑יךָ עַל־כֵּ֞ן אָנֹכִ֧י מְצַוְּךָ֛ אֶת־הַדָּבָ֥ר הַזֶּ֖ה הַיּֽוֹם׃
E lembrar-te-ás de que foste escravo na terra de Mitzrayim, e o Eterno teu Deus te resgatou; por isso eu hoje te ordeno este mandamento.
Mishneh Torah, Leavened and Unleavened Bread
In every generation, one must show himself as if he personally had come out from the subjugation of Egypt; as it is stated (Deuteronomy 6:23), "And He took us out from there, etc." And regarding this, the Holy One, blessed be He, commanded in the Torah (Deut. 5:15, 15:15, 24:22), "Remember that you were a slave" - meaning to say, as if you yourself had been a slave, came out to freedom, and were redeemed.
