Why does the Torah insert the word "Kol Oreiv"?
Chulin, 63a: Because whereas "Oreiv" refers to the black species of raven, "Kol Oreiv" includes a white species, 1 and the "Hey" in ha'Oreiv", a species of raven wih the head of a dove.
See Torah Temimah, note 55.
Why is "Oreiv" written next to "Bas ha'Ya'anah" (See note 2)?
Moshav Zekenim: Because, just like an ostrich is cruel to its children 1 , so too is a raven 2 -"Mi Yachin la'Oreiv Tzeido Ki Yeladav el Kel Yeshave'u" (Iyov 38:41).
Pesikta: It never returns to its children - as the Pasuk writes in Eichah 4:3 "l'Achzar ka'Ye'enim", and as the Navi indicates in Michah 1:8 - "ve'Eivel ki'Venos Ya'anah".
Daf Al ha'Daf (Chulin 61b, citing R. Ti'ah Veil): Why do we expound Semuchim only for Oreiv? The Torah initially taught Nesher, which has no signs of Taharah, then Peres and Ozniyah, which have one. Oreiv should have been taught next, for it has two Simanim. Rather, it was taught among the others, which have three. (Why do we need a Hekesh? It says "li'Vnei Orev Asher Yikra'u" (Tehilim 147:9)! Perhaps without the Hekesh, we would not understand this Pasuk. One who sees white babies would not know that they are ravens. - PF)
