Rabbi Abba Arey’kha (2nd century) was summoned to a region that was experiencing a drought. He instructed the people to fast, but no rain fell.
Then a man stepped forward to lead the people in prayer, and recited: “God restores the wind!” And the wind began to blow. He then exclaimed: “God sends down rain!” And the rain began to fall.
Curious about the stranger’s supernal powers, Abba Arey’kha asked him: “What is your work?”
He replied: “I am a teacher of young children, and I teach the children of the poor in same manner as I teach the children of the rich. And if anyone is unable to pay for their lessons, I will accept no form of payment from them.”
