'Swine's' in the Bible

Who sit among the graves [trying to conjure up evil spirits] and spend the night in the secret places [where spirits are thought to dwell];Who eat swine’s flesh,And their pots hold the broth of unclean meat;

“He who kills an ox [for pagan sacrifice] is [as guilty] as one who kills a man;He who sacrifices a lamb, as one who breaks a dog’s neck;He who offers a grain offering, as one who offers swine’s blood;He who offers incense, as one who blesses an idol.Such people have chosen their own ways,And their soul delights in their repulsive acts;
