Avimi Goes to Learn from His Student Rav Chisda
Avimi, who once rebuked Rav Chisda for forgetting, forgets Maseches Menachos himself and humbly travels to his own student to relearn it.
Avimi was a very demanding rebbe. His prized talmid, Rav Chisda, forgot some parts of Torah he should have known. Rav Chisda later commented that he received figurative blows from his rebbe on account of his forgetfulness.
Sometime later, the tables were turned. The rebbe, Avimi, forgot the masechta of Menachos. He went to his very own talmid, Rav Chisda, to teach it to him.
The rebbe now became the talmid. Still, the Gemara wonders why Avimi had to travel to Rav Chisda, his student, to learn from him. Avimi was Rav Chisda’s rebbe and could have summoned his own talmid to appear before him. The Gemara says simply that Avimi thought he would be more successful this way.
