He was distinguished for piety, benevolence, and learning. 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 Judah haNasi, 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 deceased friend.
