וְלֹֽא־תִקְח֥וּ כֹ֙פֶר֙ לְנֶ֣פֶשׁ רֹצֵ֔חַ אֲשֶׁר־ה֥וּא רָשָׁ֖ע לָמ֑וּת כִּי־מ֖וֹת יוּמָֽת׃
און איר זאָלט ניט אָננעמען אַן אױסלײז פֿאַר דעם נפֿש פֿון אַ מערדער װאָס איז פֿאַרשולדיקט צום טױט; נײַערט טײטן מוז ער געטײט װערן.
Shenei Luchot HaBerit
In some instances one scholar may see as many as three distinct negative commandments involving the consumption of חמץ, leavened things, whereas another scholar considers that there is only a single culpability for all of these prohibitions of חמץ, be it before Passover, during Passover, or after Passover. Even such universally known precepts as the recital of קריאת שמע, are subject to debate, one Rabbi claiming it is a Biblical precept, another saying that it is merely a Rabbinic injunction.
