9 How great and how active was the charity he showed his brethren in a time of famine, even though by then he was worn out by age and labor! He left the house where for so many years he had lived a heavenly rather than a human life and ran to Edessa. By that eloquence which Gregory of Nyssa characterized "as a key fashioned by divinity," to open the minds and the coffers of the wealthy, he castigated those who were hoarding grain and vehemently demanded that they feed the poor from their surplus. And they were touched not so much by the hunger of the citizens, as by the sincerity of Ephrem. With the money he begged, he himself provided beds for those tortured by starvation and spread them in the porticos of Edessa. There he nursed the sick and met the pilgrims who came to the city from round about looking for bread. Truly this man was placed there by divine providence to aid his country! And he did not return to solitude until the next harvest provided abundance.
