Rabbi Betta said: Rabbi Yochanan said [(see above on this matter)]: Rabbi Abba said to Betta, "Do you and Ulla disagree?" Rabbi Yitzchak said to Betta, "From here and from there," meaning from Babylonia and from Eretz Yisrael, regarding the chapter on the laws of chalitzah. And perhaps this Betta is Bar Kahana [(the text does not specify Betta Bar Kahana)].
