Leviticus 11:7

And the swine, because this [animal] divides the hoof, and makes claws of the hoof, and it does not chew the cud, is unclean to you.

And the swine, though he divide the hoof, and be clovenfooted, yet he cheweth not the cud; he is unclean to you.

The pig, because it has a split hoof, and is cloven-footed, but doesn’t chew the cud, is unclean to you.
