"The Elders of Bathyra") were a family of Jewish sages who were religious leaders around the period of the Destruction of the Second Temple.
Some tannaim are considered to belong to this family; the best known of these is Judah ben Bathyra, who resided in Nusaybin west to Babylon.
[3] As two brothers were not allowed to serve on the Sanhedrin at the same time, this suggests that the phrase "Sons of Bathyra" was not a patronymic, but a family name (nomen gentilicium).
About 100 years later, the sons of Bathyra are recorded disputing with Johanan ben Zakkai whether the shofar should be blown when Rosh Hashana falls on Shabbat.
[4] Since this takes place about 100 years after the story involving Hillel, the sons of Bathyra mentioned here must have been descendants of the earlier leaders of the Sanhedrin, who probably still retained some of their ancestors' reputation.
