Rabbi Achai bar Yashiya [Eruvin (13a), Sotah (20b), and Gittin (45a); Rabbi Achai, and in Nedarim (20a) Achah. And in Ein Yaakov Rabbi Achai]. He had a silver vessel in Nehardea and he said to give it to Rabbi Dostai bar Rabbi Yanai [(in his name)] and to Rabbi Yosi ben Kipur, as stated in the first chapter of Gittin [(14a). (In the Mekilta, Parashat Bo, Parashah 3, Rabbi Yishmael says... Rabbi Achai bar Yashiya says...
Rabbi Shimon bar Yochai says...)]. Rabbi said on the day he died in prophecy. The city of Stia in Babylon caught fish on Shabbat and Rabbi Achai bar Yashiya waited for them, as stated in the chapter of Ten Yuchasin [(2b). And it is to be questioned how he was in the days of Rabbi Yishmael and Rabbi Shimon bar Yochai and was alive at the death of Rabbi].
They were folding in the ground when a man, namely Rabbi Achai bar Yashiya, was mentioned, and Rav Nachman said to him, "But the righteous are destined to become dust." He replied, "This refers to one who has jealousy," as stated in the chapter of One Who Asks [(112b), and in the tractate of Kallah, Rabbi Yochai bar Yashiya is a typographical error. And it seems that there were two Rabbi Achai bar Yashiya, one in the days of Rabbi Dostai bar Rabbi Yanai and Rabbi Yosi ben Kipur who preceded Rabbi, and in the generation of Rabbi Shimon bar Yochai, and one at the end of Rabbi's days].
Rabbi Achai asked from Rabbi Chiya and was studying in the house of Rabbi Chiya, as Rashi explains there, "a wise man," and it seems he is the son of Yashiya during the time of Rabbi. [And I saw in Berakhot (14a) that he asked from him, "Achai" (this is his name), a Tanna of the house of Rabbi Chiya (who was studying in the house of Rabbi Chiya) from Rabbi Chiya. And in Bekhorot (24b) Rabbi Yochanan said, "He asked Achai bar Rabbi" (Rashi explains a great and important person in his generation) as mentioned above regarding Rabbi)].
