Any beast which has a division in the horn of its foot and whose food comes back into its mouth to be crushed again, may be used for food.

But even among these, there are some which may not be used for food: such as the camel, the hare, and the coney, which are unclean to you, because, though their food comes back, the horn of their feet is not parted in two.

And the pig is unclean to you, because though it has a division in the horn of its foot, its food does not come back; their flesh may not be used for food or their dead bodies touched by you.

The stork and the heron and birds of that sort, and the hoopoe and the bat.
