English: “You may eat every clean bird” — this comes to permit the bird that is set free in the purification rite of a metzora.
On the daf / in context: The seemingly superfluous “every” includes the live bird that is released over the field in the metzora ritual (Vayikra 14:7); that bird remains permitted for ordinary consumption.
Type of Learning
Derash on the inclusive language (Sifrei / Kiddushin) — “every” expands the permission.
What Is Learned
The bird released in the metzora purification remains a clean bird that may be eaten; the verse’s inclusive wording covers it.
