But only at the place that Hashem your God will choose to make His Name dwell there shall you sacrifice the Pesach in the evening, at the going down of the sun, at the season that you came forth from Egypt.
English: "There you shall sacrifice..." — I know only the owner himself; from where do I include his agent? From the verse "and you shall cook and eat." If so, why does it say "there you shall sacrifice"? Because it is improper that your offering should be sacrificed while you are occupied with your work.
On the daf / in context: An agent may perform the slaughter, yet the owner is expected to be present out of respect for the offering.
Type of Learning
Derash on the verse (Pesachim) — agency is permitted but presence is preferred.
