Leviticus 11:8

5 And the rock-badger, for the same reason, is unclean to you.

6 And the hare, because the horn of its foot is not parted in two, is unclean to you.

7 And the pig is unclean to you, because though the horn of its foot is parted, its food does not come back.

8 Their flesh may not be used for food, and their dead bodies may not even be touched; they are unclean to you.

9 These you may have for food of all things living in the water: anything living in the water, in the seas or rivers, which has special parts for swimming and skin formed of thin plates, may be used for food.

10 All other things living and moving in the water, in the sea or in the rivers, are a disgusting thing to you;

11 They may not be used for food, and their dead bodies are disgusting to you.
