Halakhah su Esodo 12:10

To not leave from the meat of the Pesach sacrifice: To not leave any of the meat of the Pesach sacrifice to the next day (overnight), which is the fifteenth of Nissan, as it is stated (Exodus 12:10), "You shall not leave any of it over until morning."

And [it] is practiced by males and females at the time of the [Temple]. And one who transgresses it and leaves [it] over violates a negative commandment. And we do not give lashes for this negative commandment, since it is rectifiable by a positive commandment (Mishneh Torah, Laws of Paschal Offering 10:11) - as it is stated (Exodus 12:10), "and that which remains until the morning, you shall burn with fire." And it is a law that we do not give lashes for [the transgression of] a negative commandment that is rectifiable by a positive commandment.

The commandment of the burning of the remnant (notar) of the [sacrifices]: That we were commanded to burn the notar - and that is meat of the [sacrifices] that remains after the time limited for their eating has passed - as it is stated (Leviticus 7:17), "And the notar of the meat of the sacrifice on the third day, it shall be brunt with fire." And this burning is a positive commandment - as so they say in Mekhilta concerning Pesach (Exodus 12:10), "'You shall not leave any of it, etc., and the notar you shall burn with fire, etc.' - the verse comes to give a positive commandment upon the negative commandment." It is implied that the commandment of burning notar is a positive commandment. And the law of piggul and notar are the same in this, that there is also a positive commandment in its burning, such that we have found Scripture expressing piggul, with the word, notar.
