Rabbah Fears the Pangs of Mashiach
Abaye asks Rabbah why he fears the travails before Mashiach when he has Torah and chesed; Rabbah answers that his sins may still expose him.
The Gemara there says that Rabbah was afraid of the pain and travails that will herald the arrival of Mashiach. Abaye asked Rabbah, “Why are you afraid? Rebbe Eliezer says that one who wishes to be spared the pain that will precede Mashiach should busy himself in Torah and chesed. And you, Rebbe, have both!” Rabbah answered that he was afraid that perhaps sins he committed would make him susceptible to those pains.
