Cain and the Wandering Jew

"...or went away at night, he would slouch out, like Cain or the Wandering Jew, as if he had no idea where he was going..." (Dickens 146).

Cain was a son of Adam and Eve, along with his brother, Abel. He became jealous that God liked a sacrifice Abel gave more than his, and killed his brother, thus committing the first murder.

The Wandering Jew was a Jew who taunted Christ when they were on their way to Jesus' crucifixion. He was then sent away by Christ upon his resurrection, and destined to wander the earth with no home or respect for the rest of his life.

By comparing Orlick to these two men, Pip is making a very pointed remark, and adding a good deal of foreshadowing. Later in the book, Orlick attacks Mrs. Joe, Pip's sister, giving her great injuries. These references foreshadow this fact; at the point in the book where they are stated, Orlick still seems like a good man, although a little odd. However he represents himself later, in attacked Mrs. J, as a figure of evil in the novel.
