Musar sur Le Lévitique 1:17

וְשִׁסַּ֨ע אֹת֣וֹ בִכְנָפָיו֮ לֹ֣א יַבְדִּיל֒ וְהִקְטִ֨יר אֹת֤וֹ הַכֹּהֵן֙ הַמִּזְבֵּ֔חָה עַל־הָעֵצִ֖ים אֲשֶׁ֣ר עַל־הָאֵ֑שׁ עֹלָ֣ה ה֗וּא אִשֵּׁ֛ה רֵ֥יחַ נִיחֹ֖חַ לַיהוָֽה׃ (ס)

Alors le pontife ouvrira l’oiseau du côté des ailes, sans les détacher, puis le fera fumer sur l’autel, sur le bois du brasier. Ce sera un holocauste, combustion d’une odeur agréable au Seigneur.

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.
