Rabbi Ami and Rabbi Asi No Complaints About the Weather
When it became too hot in the place where two great Talmudic Sages, Rabbi Ami and Rabbi Asi, were engaged in Torah study, they moved to a shadier spot. When the winter cold became too intense where they were studying they moved to a warmer spot. They went to this trouble, explains Rashi (Mesechta Ketubot 112b ), in order to avoid complaining about the weather in Eretz Yisrael .
It must be assumed that these two Sages could have continued their studies where they were despite the heat or cold. Making the move to a more comfortable place probably entailed a loss of precious time which could have been dedicated to intense Torah study. They nevertheless were prepared to make this sacrifice to avoid the temptation of complaining about the weather of the land they loved.
