What are some Jude the obscure quotes explained?

Jude and Arabella go to an inn to get a drink on their outing together. "They sat and looked round the room, and at the picture of Samson and Delilah which hung on the wall" (47). In The Bible, Delilah is responsible for Samson's loss of power. Delilah betrays and deceives her partner much in the same way Arabella deceives Jude.
