רבין בר רב אדא

Ravin bar Rav Ada is an amora who appears across many tractates of the Talmud. He is repeatedly recorded conveying statements in the name of Rabbi Yitzchak, frequently in the form of case-precedents (“a story occurred”) that came before Rabbi or other authorities. These include cases of ritual immersion invalidated by an obstruction (Niddah), an eruv-passageway abutting the sea and a refuse-heap (Eruvin), questions of kilayim (forbidden mixtures in a field), and a leavened deposit gnawed open by mice that was brought before Rabbi for a ruling (Pesachim, Bava Metzia). His Rabbi Yitzchak traditions also include aggadic teachings in Berakhot on the Divine presence in the synagogue and on the importance of regular attendance.

He is likewise depicted in dialogue with Rava, repeatedly raising the objections of “your students” who cited a baraita reported by Rav Amram, on matters of the sacrificial order — the burning of limbs and fats by night, the laundering of garments splashed by sprinkled blood, and the status of a communal sin-offering (Menachot, Zevachim, Yoma). He also appears alongside Rabbah bar Rav Ada with the betrothal blessing in the name of Rav Yehuda (Ketubot), and is recorded on dietary-law questions in Chullin.
