In Ezekiel 23, one of the themes is about moral decay and the consequences of straying from the right path. In Pulp Fiction, a theme could be the randomness of life and how violence can be intertwined with normalcy. There is a contrast between the religious - based moral exploration in Ezekiel 23 and the more secular, post - modern look at life in Pulp Fiction.
