Rabbi Eleazar, son of Rabbi Yanai, during the time of Rabbi Yochanan. He was the teacher of Rabbi Eleazar, son of Antigonus. [I do not know who conveyed this prophecy to him, whether it was because Rabbi Eleazar, son of Antigonus, said it in the name of Rabbi Eleazar, son of Rabbi Yanai, in Gittin (31a), for we also find that Rabbi Eleazar, son of Rabbi Yanai, said in the name of Rabbi Eleazar, son of Antigonus, in Beitzah (34a).
And regarding the statement that he was during the time of Rabbi Yochanan, refer to the discussion nearby.]
