Rabbi Yehudah HaNasi tasks Levi with characterizing several different segments of society. Plus, more comments from R. Yehudah HaNasi, on his deathbed. Also, more tracking the lineages of the Babylonians, and Rabbi Meir's opposing view on the purity of the various lines in contrast to the sages in general. With practical implications. Also, how the mamzerim will (or will not) become pure in the time of the World to Come. And the shift in meaning for the word "mamzer."
