וְלֹא־יִזְבְּח֥וּ עוֹד֙ אֶת־זִבְחֵיהֶ֔ם לַשְּׂעִירִ֕ם אֲשֶׁ֛ר הֵ֥ם זֹנִ֖ים אַחֲרֵיהֶ֑ם חֻקַּ֥ת עוֹלָ֛ם תִּֽהְיֶה־זֹּ֥את לָהֶ֖ם לְדֹרֹתָֽם׃
他們不可再把祭牲獻給鬼魔，就是他們隨從行邪淫的那些鬼魔。這要作他們世世代代永遠的定例。
Shenei Luchot HaBerit
When Jacob describes Esau his brother as a hairy man, whereas he himself was smooth-skinned, he referred to the Esau of this world, and he alluded to Esau's power in the "higher" world by mentioning that he was איש שעיר. He referred to Esau as the קטרוג, the perennial accuser of man. Bereshit Rabbah 65,15 understands the word Sa-ir as identical with the one mentioned in Leviticus 17,7: ולא יזבחו עוד לשעירים, "so that they will no longer offer sacrifices to the demons." The word Chalak, is equated by that Midrash with the word Chelek, as in כי חלק ה' עמו, יעקב חלק נחלתו, "G–d's share is His people, Jacob is His inheritance" (Deut. 32,9). We know from Succah 52a that Satan is more prone to attack a Torah scholar than anyone else.
