Why does the Torah write "Ya'asu oso" (and not 'Ya'asuhu'. See Torah Temimah, note 24)?
Pesachim, 95a: To teach us that one should make every effort to avoid bringing a Korban Pesach for oneself only. 1
See Torah Temimah, note 24, who elaborates.
What is ke'Chol Chukas ha'Pesach Ya'asu oso" coming to teach us?
Pesachim 95a: It comes to incorporate MItzvos directly connected with the body of the Pesach - 'Seh Tamim, Zachar and Ben Shanah'. 1
Pesachim 95a: "Al Matzos u'Merorim"m - in Pasuk 11 - includes what is connected with the body of the Pesach, and "ve'Etzem Lo Sishb'ru Bo" precludes what is not connected to it - such as destroying the Chametz. See Torah Temimah note 22.
What is the significance of the fact that the Torah inserts three P'ratim - "Al Matzos u'Merrorim Yochluhu" (in Pasuk 11), "Lo Yash'iru mimenu Ad Boker" and "ve'Etzem Lo Yishb'ru bo", and one K'lal - "ke'Chol Chukas ha'Pesach Ya'asu oso"?
Pesachim, 92a: They form a "P'rat u'Chelal, from which we learn one inclusion regarding each P'rat of the Pesach Sheini, and one exclusion: "Al Matzos u'Merorim Yochluhu", (an Asei), includes "Tz'li Eish" - and precludes "Tashbisu Se'or ? "; 1 "Lo Yash'iru mimenu Ad Boker" (a La'av ha'Nitak la'Asei) includes "Lo Sotzi mimenu Chutzah" and precludes ""Lo Yera'eh ve'Lo Yimatzei"; "ke'Chol Chukas ha'Pesach Ya'asu oso" (a regular Lo Sa'aseh) includes "Al Tochlu mimenu Na" and precludes "Lo Sishchat al Chametz Dam Zivchi".
Pesachim Ibid.: Each case includes a Mitzvah connected with the body of the Pesach - like the K'lal - ke'Chol Chukas ha'Pesach ? ", and precludes a Mitzvah that is not connected to it.
