Mar Rav Yehuda [(Rash"b Yuchsin wrote: his grandfather was the father of his father)] son of Mar Rav Shmuel was Rosh Kallah in Pumbedita in the year 4665, and reigned for thirteen years and passed away in Adar 4676, year 1228 of contracts. David son of Zakkai from the House of David was of royal seed; he was the Exilarch in the days of the aforementioned Rav Yehuda Gaon. [And this is the dispute between the Rabban of the Yeshiva and David, the Nasi of the Yeshiva: they forced him and called him Mar Mevasser Gaon son of Mar Rav Kimoi Gaon, and David the Nasi called Mar Rav Kohen Tzedek son of Mar Rav Yosef.

And there was a dispute between them from 4676 until Elul 4680, five years. And the servant Shlomo, David the Nasi, made with Rav Mevasser, and Rav Mevasser Gaon and Rabban remained alone. And the distinguished ones of the Rabban were in joy, and Mar Rav Kohen Tzedek and Rabban remained alone. Yuchsin in the letter of Rash"b].
