Deuteronomy 14:7-11

However, you are not to eat these among the ones that chew the cud, or among those that have the hoof divided in two: the camel, the rabbit, and the rock hyrax, for though they chew the cud, they do not have a divided hoof; they are unclean to you.

And the pig, because it has a divided hoof but does not chew the cud, it is unclean for you. You shall not eat any of their flesh, nor touch their carcasses.

“You may eat any clean bird.
