Why does the Torah repeat the Parshah of Arayos?
Rashi: Parshas Acharei-Mos discusses the warnings, and Kedoshim, the punishments.
Moshav Zekenim (in 19:35): It is placed near false measures to teach us that their punishment is harsher than Arayos, since, as opposed to Arayos, it is impossible to do Teshuvah properly. 1
Moshav Zekenim (in Pasuk 9): [Even though the Torah already taught Kareis for all of the Arayos in Acharei-Mos - 18:29], it now adds Misah to many of the cases; It mentions Nidah and aunts to incorporate Ha'ara'ah, and "Dodaso" to include Ariri (dying childless). Also Kareis for a sister is discussed in more detail. 2
Why does the Torah repeat the word "Ish"?
Chagigah, 11b: To include Nochrim in the La'av of Avodah Zarah. 1
See Torah Temimah, note 1, who asks tha we already know this from other sources and establishes the D'rashah by Molech exclusively.
What is the definition of 'Molech?
Rashi: Refer to 18:21:5:1* - and See Rashi Sanhedrin, 64b DH 'Sh'raga de'Livni'. 1
Ramban: Refer to 18:21:3:2*.
Targum Yonasan: Refer to 18:21:2:3 and notes..
Oznayim la'Torah: Where Rashi explains that the son did not necessarily die, even though Rashi himself, in Yirmiyah, 4:31, writes that the child is burned to death? See Oznayim la'Torah DH 'Asher Yiten mi'Zar'o la'Molech', who elaborates.
What are the connotations of "Am ha'Aretz"? Why does the Torah use that term?
Rashi #1: The Torah refers to Yisrael as "Am ha'Aretz" because the world was created on their behalf. 1
Rashi #2, Targum Onkelos and Targum Yonasan 2 : Yisrael are so-called here because it is by keeping these Mitzvos that they will inherit Eretz Yisrael.
Ramban and Seforno: To teach us that all the people are obligated to participate in the stoning of the sinner. 3
Oznayim la'Torah: Refer 20:2:3:2**.
Having stated "Mos Yumas" (at the hand of Beis-Din), why does the Pasuk add "Am ha'Aretz Yirgemuhu ba'Aven"?
Rashi: To teach us that, if Beis-Din are unable to carry out the death-sentence, 1 then the people should do so.
Ramban and Moshav Zekenim (both in Pasuk 3), Seforno and Targum Yonasan: It means that, in their zealousy 2 for Hashem's honor, 3 the people should put to death the perpetrator (provided there are witnesses and warning - Seforno).
Presumably this was likely to happen due to the power and influence of the priests, who would back the father - See Oznayim la'Torah DH 'Am ha'Aretz ... '.
Over the horrific crime.
Oznayim la'Torah: And because, due to the nature of the crime, which goes against everything that Torah represents and causes the Shechinah to depart from Yisrael and Yisrael to fall in battle and to exile them from their land - in which case the people who want toremain in the land need to take action and punish the perpetrater via the most stringent of all the death-penalties, to prevent all this from taking place. And this also explains the multiple expressions of Hashem's reactions in the next Pasuk.
What is the connection between this Parshah and the previous one?
Seforno: After presenting how to emulate Hashem 1 as far as is humanly possible, the Torah now switches to the punishments for those who render themselves Tamei in one of three areas that are the very antithesis of holiness: 1. In the area of false ideologies. 2 2. In the area of adultery. 3 3. In the area of forbidden food. 4
By sanctifying ourselves like Him. Refer to 19:2:2:3, and as the Seforno explained throughout the Parshah.
Seforno: Such as Molech and Ovos and Yid'onim (discussed in the previous chapter), by both of which the Torah mentions Tum'ah (in the following Pasuk here and in Pasuk 31 there, respectively).
Seforno: See above, in Acharei-Mos, 18:24.
Seforno: See later in 20:25.
