English: “And he shall cleave it” — it, the valid one, and not the disqualified.
In Sifra: The pronoun “oto” restricts the obligation of shisa to a valid bird. A bird that is already pasul is not subject to the requirement of being cleft.
Type of Learning
Miyut from “oto” — shisa required for the valid, not the pasul.
What Is Learned
Shisa is required for a valid bird olah; a pasul need not be split. The verse’s “oto” selects the kosher specimen as the object of the cleaving obligation and excludes the disqualified from that requirement.
