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׃
你吃逾越節祭肉的時候不可吃有酵的餅；七日之內，你要吃無酵餅，就是困苦的餅，因為你出埃及地是急忙的，好讓你一生的日子都記得你出埃及地的那一日。

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).
Ibn Ezra
you must not eat leaven on it meaning, no leaven may remain at the time when one may slaughter the Paschal offering [Pesaḥim 28b].
Sforno
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.

כי בחפזון יצאת FOR THOU CAMEST FORTH [FROM THE LAND OF EGYPT] IN HASTE, and the dough therefore had no time to become leavened, and this (the eating of unleavened bread) shall be unto you as reminder of this. The haste, spoken of here, was not on thy part, but on Egypt’s part, for so it states, (Exodus 12:33) “And Egypt was urgent upon the people [hastening to send them out of the land]” (Sifrei Devarim 130:6; cf. Berakhot 9a).
