On the status of Jerusalem. Specifically with regard to ritual Impurity. How does the city itself compare to synagogues and batei midrashot? Is Jerusalem on the portion of the tribes whose portions are right there (Yehuda and Binyamin), or is it "everyone's"? What does it mean to be host, as compared to guest, when thinking of the holy city (and also on general)? Also, the "understudy" of the kohen gadol - when does the new status take place, depending on when the kohen gadol was disqualified? And how was the transfer to be evident to the rest of the people there? Perhaps a straw man, but apparently via his belt. The garments here just might make the man. Or perhaps he attains the kohen gadol status simply by virtue of doing the job. Plus, the question of what happens if the first kohen gadol can come back on the job? What happens to the understudy who has been elevated? It would seem he's in limbo (unless the first kohen gadol eventually dies...).
