רבי אייבו

Rabbi Ayvu was an amora whose teachings are preserved in several tractates of the Talmud. He often brings rulings in the name of Rabbi Yannai: in Zevachim he states a teaching that excludes one who pledges an olah toward the upkeep of the Temple, and in Ketubot he brings Rabbi Yannai’s principle that a condition written into the ketubah carries the same force as the ketubah itself, a view cited in the discussion of the additional sum (tosefet).

Under the fuller name Rabbi Ayvu bar Nagri he appears alongside Rabbi Chiya bar Abba. In Sanhedrin he brings, in the name of Rabbi Chiya bar Abba, an explanation distinguishing the terms used for the Egyptian magicians — one referring to the work of demons and the other to acts of sorcery, supported by the verse describing the revolving flaming sword. In Rosh Hashanah the two are recorded traveling to a place reached by the messengers of Nisan but not those of Tishrei, where they observed a single day; when Rabbi Yochanan heard, he was displeased and reminded them of his instruction to keep two days as a safeguard.
