Rava the Amora
From Zissil
Rava was a fourth generation Babylonian Amora and a friend of Abaya, with whom he argues many times throughout the Talmud. A student of Rav Nachman, Rava later became head of the Pumpadisa academy after the passing of Abaya and its relocation to Mechuza.
Kever Rava
Rava is buried in a cave in Ovnit, North Israel along with Abaya, Rav Demei of Naharada and a number of other unnamed Tzadikim.
Hillula of Rava
Local residents of the area created a Hillula for Rava and Abaya which they celebrate on the 28th of Iyyar.
