Deuteronomy 14:5

2 For you are a holy people to the Lord your God, and the Lord has taken you to be his special people out of all the nations on the face of the earth.

3 No disgusting thing may be your food.

4 These are the beasts which you may have for food: the ox, the sheep, and the goat;

5 The hart, the gazelle, and the roe, the mountain goat and the pygarg and the antelope and the mountain sheep.

6 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.

7 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.

8 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.
