וְלֹא־יִזְבְּח֥וּ עוֹד֙ אֶת־זִבְחֵיהֶ֔ם לַשְּׂעִירִ֕ם אֲשֶׁ֛ר הֵ֥ם זֹנִ֖ים אַחֲרֵיהֶ֑ם חֻקַּ֥ת עוֹלָ֛ם תִּֽהְיֶה־זֹּ֥את לָהֶ֖ם לְדֹרֹתָֽם׃
et ils n’offriront plus leurs sacrifices aux démons, au culte desquels ils se prostituent. Que cela soit une loi immuable pour eux, dans leurs générations.
Mishnah Chullin
In certain respects the prohibition of the fat is stricter than the prohibition of the blood, and in certain respects the prohibition of the blood is stricter than the prohibition of the fat. The prohibition of the fat is stricter, in that the fat is subject to the law of sacrilege, and one is obligated over it for piggul, notar, and uncleanness which is not the case with the blood. And the prohibition of the blood is stricter, for it applies to cattle, wild animals and fowl, whether clean or unclean; but the prohibition of the fat applies to clean cattle only.
