David and the Sacred Bread

I really need help on this study.
Did you ever run across one of those Bible Studies that was so easy to find the link between the New Testament story and the Old Testament story but the more you looked into it, you found a host of spiritual words and symbols but no clear connection between them. This is one of those rare Bible Studies that has so many directions to take you don’t know where to begin and no idea where the lessons are leading.
