ר' אבין בר רב נחמן

Rabbi Avin, son of Rav Nachman, said to Rav Yehuda: "Avin, brother of [do not sell the land that is adjacent to the city (Baba Metzia 107a, Baba Batra 94b). Rabbi Ravin, son of Rav Nachman, taught, and the genealogies also brought in the name Rabbi Ravin, and there is a typographical error there. Rabbi Ravin, son of Nachman, raised a question, as Rava said, etc. (Yevamot 84b)]."
