What is this Pasuk coming to teach us?
Rashi (citing the Sifra): It teaches us that someone who eats the Neveilah of a Tahor (Kasher) bird 1 becomes Tamei, and is forbidden to eat Kodshim (or to enter the Beis-Hamikdash). 2
Ramban, Moshav Zekenim, Targum Onkelos and Targum Yonasan: It is a warning against eating Neveilos (animals that died without Shechitah) and T'reifos 3 (that were mortally wounded) - by a lion or a bear. He will become Tamei (through moving or touching them) and forbidden to eat Kodshim until the night after he Tovels.
Rashbam: It teaches us that a Kohen is forbidden to eat the Neveilah of a Tamei bird. 4
Chulin 100b: Not of a Tamei bird, which is Asur because it is Tamei and not because it is a Neveilah.
Ramban and Moshav Zekenim: The Torah discusses eating them because people are prone to eat them, whereas it warns aginst touching Sheratzim, because they disgust people, and are not normally eaten.
Having already taught us this Halachah (11:39), why does the Torah repeat it here?
Rashbam: Bearing in mind that the Torah is speaking here to the Kohanim, it teaches them that, even though they are permitted to eat a Chatas ha'Of on which Melikah was performed (and which is therefore technically a Neveilah), they are not permitted to eat any other form of Neveilah. 1
Why does the Torah add the word "Letam'ah bah"?
