The end of chapter 2, and the beginning of chapter 3. First, a killer who goes into exile must be upfront about why he's in exile. And in the event of people wanting to honor him, he would need to protest just the once. But not more. The chapter closes with a dispute. Also, the beginning of chapter 3, with its first mishnah -- namely, for when people get lashes. Plus: who and why the Givonim? Note: The Gemara explains the view that says - for every violation of karet, one also gets lashes, but not everyone agrees with that! So the Gemara presents the 3 opinions on this topic, only one of which is represented in the mishnah - specifically, that of Rabbi Akiva.
