“And every animal that parts the hoof,
which is split into two (shosa`at shes`a) and ruminates its cud” (Dt.14:6).
Unless it possesses all three of these signs,
it is not permitted as food.
Abba Hanan, in the name of R. Eliezer, says:
[the animal known as] the split one (shasu`ah)
is a kind of wild cattle.
[“Any clean bird you may eat” (Dt.14:11)].
Said R. Yoshaiah:
Any place [in Scripture] that specifies bird—
the verse is identifying a clean one
[that may be eaten].
Said R. Isaac:
clean fowl is called fowl and it is called bird.
But an unclean one
is never called anything but fowl. 2
[“The buzzard, the falcon, and the kite” (Dt.14:13)] —
the kite (dayah)—it is a falcon (ayah).
And, in fact, they are all a kind of kite.
Isi b. Judah says:
there are 100 types of fowl in the East,
and all of them are a kind of falcon.
[One verse states]
“The buzzard (ra’ah), the falcon (‘ayah), and the kite” (dayah),
and any kind of raven (`oreiv)” (Dt.14:13).
[yet another verse states:]
“The falcon, the kite (da’ah), the buzzard . . . and any kind of raven” (Lv.11:14)—
why is this [list of unclean animals (Lv.11:1-47)]
restated in the Repetition of the Torah (Dt. 14:3-21)?
[Regarding] the cattle, because of the split one (shasu`ah),
and [regarding] the fowl—because of the kite,
[which is known as dayah (Dt.14:13) and da’ah (Lv.11:14)]3
