The opening as it read in 2015

Abba bar Abba ( Aramic : אבא בר אבא , or Father of Samuel , Aramic : אבוה דשמואל ; Cited in the Jerusalem Talmud as Abba bar Ba , Aramic : אבא בר בא ) was a Jewish Talmudist who lived in Babylonia , known as an amora of the 2nd and 3rd centuries, distinguished for piety, benevolence, and learning.1 He is known chiefly through his son Samuel of Nehardea , principal of the Academy of Nehardea , and is nearly always referred to as "Samuel's father." Abba traveled to Palestine , where he entered into relations with R. Judah I , the patriarch, with whose pupil Levi bar Sisi he was on terms of intimate friendship. When Levi died Abba delivered the funeral oration and glorified the memory of his friend.2
