A long discussion of the sins of King David... and yes, it's a long list. Largely, and perhaps unsurprisingly, related to issues of lust. (In contrast to other interpretations by the sages that he did not sin at all - in the same events). Also, Yehoshua ben Perahiah and his student Jesus - and their sojourn in Egypt (and travels back), when King Yannai was killing sages.
