Дварим 15:15 Галаха: Mishneh Torah, Leavened and Unleavened Bread

וְזָכַרְתָּ֗ כִּ֣י עֶ֤בֶד הָיִ֙יתָ֙ בְּאֶ֣רֶץ מִצְרַ֔יִם וַֽיִּפְדְּךָ֖ יְהוָ֣ה אֱלֹהֶ֑יךָ עַל־כֵּ֞ן אָנֹכִ֧י מְצַוְּךָ֛ אֶת־הַדָּבָ֥ר הַזֶּ֖ה הַיּֽוֹם׃

И помни, что ты был рабом в земле Египетской, и Господь, Бог твой, искупил тебя; поэтому я приказываю тебе это сегодня.

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.
