Rabbah bar Nahmani was born in Babylon c. 270 into a priestly family.
He studied at both the academies in Sura and Pumbedita.
He was for twenty-two years head of the Academy at Pumbeditha. His great dialectic skill acquiredfor him the epithet "uprooter of mountains. " The Talmud owes much to this rabbi. He is said to have perished in a jungle into which he had fled from the officers of the Persian king.
He was a great scholar, renowned for his abilities to argue texts, resolve contradictions, and find applications, which gave him the nickname of "oker harim" or 'uprooter of mountains', as the Talmud says that when he was in argument, he got so worked up that he appeared to pick up mountains and grind them against each other.
