A complicated daf.... with a textual comparison of biblical verses, focusing on the words "neveilah" and "treyfah" - both of which are now defined. With many categories and permutations of both, and each, when it comes to different kinds of animals. Plus, a more straightforward passage on the unusual terms of the birds with melikah, when the bird has a blemish, and then in comparison to unusual animal (non-bird) offerings, such as a goat, and then, finally, a focus on the "eglah arufah," the heifer who is then considered its own category.
