R. Yishmael says: That verse (Devarim 16:2) ("sheep and cattle") speaks of the chagigah that is brought on Pesach. You say this, but perhaps it speaks of the Pesach itself? "An unblemished lamb, a male" speaks of the Pesach itself. How, then, am I to understand "And you shall slaughter the Pesach to your G–d (sheep and cattle)"? As referring to the chagigah that comes with the Pesach.
