רב המנונא בריה דרב אדא בר אהבה

Rav HaMnunah, the son of Rav Ada bar Ahavah [in the Midrash Kohelet, it is stated: "On the day that Rav Ada bar Ahavah died, Rav HaMnunah, his son, was born.

On the day that Rav HaMnunah died, Rabbi Avin, his son, was born." However, in Bereishit Rabbah, it states that on the day Rav HaMnunah died, Rabbi Avin was born, and it does not mention the word 'son.']
