Weekly Tzedaka Torah Once a pauper possessing only a silver coin worth half a Ma’ah (currency used at the time) passed in front ofRebbe Yitzchak. He requested that Rebbe Yitzchak contribute and supplement this amount, allowing his family to survive. Rebbe Yitzchak replied that all he had was an additional half a Ma’ah and even were he to give that, it would not be sufficient for the family’s survival. After the pauper responded; that combined with his own half a Ma’ah he will be able to manage, Rebbe Yitzchak pulled out his coin and handed it to him.
They showed Rebbe Yitzchak in a dream that he was passing on the shore of the Great Ocean and they were trying to throw him inside. He saw Rebbe Shimon stretch out his hand but he as unable to reach it. Suddenly the pauper came and saved him, pulling him out of the ocean and handing him to Rebbe Shimon. When he awoke, the following verse fell into his mouth, “Fortunate is he who considers the poor; on a bad day Hashem will rescue him.” Zohar Shemos Page 61B
