לֹא־תֹאכַ֤ל עָלָיו֙ חָמֵ֔ץ שִׁבְעַ֥ת יָמִ֛ים תֹּֽאכַל־עָלָ֥יו מַצּ֖וֹת לֶ֣חֶם עֹ֑נִי כִּ֣י בְחִפָּז֗וֹן יָצָ֙אתָ֙ מֵאֶ֣רֶץ מִצְרַ֔יִם לְמַ֣עַן תִּזְכֹּר֔ אֶת־י֤וֹם צֵֽאתְךָ֙ מֵאֶ֣רֶץ מִצְרַ֔יִם כֹּ֖ל יְמֵ֥י חַיֶּֽיךָ׃
유교병을 그것과 아울러 먹지 말고 칠 일 동안은 무교병 곧 고난의 떡을 그것과 아울러 먹으라 이는 네가 애굽 땅에서 급속히 나왔음이니 이같이 행하여 너의 평생에 항상 네가 애굽 땅에서 나온 날을 기억할 것이니라
Rashi on Deuteronomy
לחם עני THE BREAD OF AFFLICTION — i.e. bread that calls to mind the affliction to which they were subjected in Egypt (Sifrei Devarim 130:5).
Sforno on Deuteronomy
לא תאכל עליו חמץ שבעת ימים, even though in Egypt the prohibition of eating chametz was in effect for only one day, as our sages pointed out in Pessachim 96.
Rabbeinu Bahya
לא תאכל עליו חמץ, “Do not eat any leavened matter with it.” This refers already to the time when the Passover sacrifice may be slaughtered, i.e. about midday. At that time one must no longer own anything leavened (Ibn Ezra).
