Sefer HaChinuch ספר החינוך

To not eat notar: To not eat notar — and that is what remains from the meat of consecrated animals, from a sacrifice that was brought according to its commanded [specifications] after the time that it is fit to eat from it, as it is stated about the inauguratory sacrifices (Exodus 29:33), “it shall not be eaten, they are holy.” And the explanation came about this (Meilah 17b), “[It refers to] anything that is consecrated [that is] disqualified, to give a negative commandment on its eating.” And this is hinted to by the verse, in its stating, “they are holy”: This third person, which is “they,” includes all that which is disqualified of the consecrated animals. But we should not learn from this that notar and piggul (sacrifices disqualified by the wrong thought) are considered one negative commandment, as they are two topics — as I have written above on the prohibition of piggul in the Order of Tsav (Sefer HaChinukh 144). And we found about them that two [different] verses came concerning the punishments, as it is written (Leviticus 7:18), “And if it is surely eaten, etc.”; and it is written, after it, “and the soul that eats it will carry its iniquity” — and this carrying of iniquity is excision, as we learn from a comparison with notar. As here, it is written concerning notar (Leviticus 19:6-8), “and that which remains to the third day[...] is pigul, it is not acceptable. And one who eats them will carry his iniquity, since he profaned the holy of God, and excised, etc.” And hence, even if the warning for both of them is from one verse, it is not made impossible because of this to consider them two [separate] negative commandments. And so did they say in Meilah 17b, “Piggul and notar do not combine because they are two topics, etc.” — as it is explained there that there are things that do not combine and there are things that combine.

I have written what I have known about the roots of the matter in the prohibition of piggul.

From the laws of notar is that which they, may their memory be blessed, said (Zevachim 35a) [that if one] ate from the skin, from the gravy, from the spice, from the remnants of meat stuck to the skin, from the crop, from the sinews, from the horns, from the hooves, from the nails, from the beak, from the eggs of the bird and from its feather, he is not liable for excision. And so [too,] with blood (Zevachim 45b), one is not liable on account of notar; and so [too,] with the frankincense, the incense and the wood, as we wrote about piggul. But [if he ate] from the embryo or from the placenta, he is liable for excision. And so [too,] what they said (Zevachim 45a) that consecrated animals of the gentiles — meaning to say vows and pledges that we accept from them — do not have [liability] on account of notar and piggul. [These] and the rest of the details of the prohibition of notar — and also of piggul — are elucidated in many places in the Order of Kodashim. (See Mishneh Torah, Laws of Sacrifices Rendered Unfit 1.)

And this prohibition is practiced at the time of the [Temple] by males and females. And one who transgresses it and eats a kazayit of notar volitionally is liable for excision; and he is obligated to bring a fixed sin-offering, if inadvertent. And so [too,] is the law if he ate a kazayit of notar and piggul in combination — since with regards to eating, they combine. (See Meilah 17b.)
