Pesachim 95A

מתני׳ מה בין פסח הראשון לשני? הראשון אסור ב״בל יראה״ ו״בל ימצא״, והשני ⁠— חמץ ומצה עמו בבית. הראשון טעון הלל באכילתו, והשני אינו טעון הלל באכילתו. זה וזה טעון הלל בעשייתן, ונאכלין צלי על מצה ומרורים, ודוחין את השבת.

Mishnah: What is the difference between the Paschal lamb offered on the first Pesaḥ and the Paschal lamb offered on the second Pesaḥ? On the first Pesaḥ, at the time of slaughtering the Paschal lamb, it is prohibited to own leavened bread due to the prohibitions: It should not be seen, and: It should not be found. And on the second Pesaḥ it is permissible for one to have both leavened bread and matza with him in the house. Another difference is that the Paschal lamb offered on the first Pesaḥ requires the recitation of hallel as it is eaten and the second does not require the recitation of hallel as it is eaten. However, they are the same in that the Paschal lambs sacrificed on both the first and second Pesaḥ require the recitation of hallel as they are prepared, i.e., as they are slaughtered, and they are both eaten roasted with matza and bitter herbs, and they override Shabbat in that they may be slaughtered and their blood sprinkled even on Shabbat.

גמ׳ תנו רבנן: ״ככל חוקת הפסח יעשו אותו״⁠ — במצוה שבגופו הכתוב מדבר.

Talmud: A baraita states a halakhic midrash pertaining to the Paschal lamb offered on the second Pesaḥ. The verse states with regard to the second Pesaḥ: “They should leave none of it to the morning, nor break a bone in it; according to all the entire statute of the Paschal lamb they should offer it” (Numbers 9:12). The fact that the verse says “it” indicates that the verse is speaking of a mitzva applicable to the body of the Paschal lamb, meaning that halakhot pertaining to the actual Paschal lamb on the first Pesaḥ apply equally to the Paschal lamb on the second Pesaḥ.
