If you were teaching a course on Jewish Backgrounds to Early Christianity what primary (or secondary) texts would you assign? What would the main issues be? What are the most important features of Second Temple Judaism for an understanding of early Christianity?
(I don't really like the course title because it can suggest that Judaism is only important for the light it sheds on early Christianity, not something worth studying on its own terms. But it occurred to me, as I began revising my syllabus for next semester's class, that taking the 'backgrounds' part seriously is a good way of asking the 'so what?' question.)
