'Pig's' in the Bible

Like a gold ring in a pig's snout is a beautiful woman who rejects discretion.

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.
