The pig is unclean to you because its hoof is divided( the hoof is completely split in two), even though it does not chew the cud.You must not eat from their meat and you must not touch their carcasses; they are unclean to you.
The one who slaughters a bull also strikes down a man; the one who sacrifices a lamb also breaks a dog’s neck; the one who presents an offering includes pig’s blood with it; the one who offers incense also praises an idol. They have decided to behave this way; they enjoy these disgusting practices.
Also the pig is ritually impure to you; though it has divided hooves, it does not chew the cud. You may not eat their meat or even touch their remains.
