Swine

Pig and pork: repeatedly named as unclean, and a vivid symbol of exile and degradation.

Scripture

Leviticus 11:7

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

Isaiah 65:4

4 who sit among the graves, and lodge in the secret places; who eat pig's flesh, and broth of abominable things is in their vessels;

Luke 15:16

16 He wanted to fill his belly with the husks that the pigs ate, but no one gave him any.
