A similar thing befell the son of the great and extremely pious scholar Rabbi Reuben. To him came the Angel of Death and announced that his only son would have to die. The pious man was resigned: "We mortals can do nothing to oppose a Divine decree," he said, "but I pray there, give him thirty days' respite, that I may see him married." The Angel of Death acquiesced.
The Rabbi told no one of this encounter, waited until the appointed time was drawing to a close, and, on the very last day, the thirtieth, he arranged his son's wedding feast. On that day, the bridegroom-to-be met Elijah, who told him of his approaching death. A worthy son of his father, he said: "Who may oppose God? And am I better than Abraham, Isaac, and Jacob?
They, too, had to die." Elijah told him furthermore, that the Angel of Death would appear to him in the guise of a ragged, dirty beggar, and he advised him to receive him in the kindliest possible manner, and in particular he was to insist upon his taking food and drink from him. All happened as Elijah had predicted, and his advice, too, proved efficacious, for the heart of the Angel of Death, who finally revealed his identity with the beggar, was softened by the entreaties of the father, combined with the tears of the young wife, who resorted to the argument cited above, of the year of exemption from duty granted to the newly-married.
The Angel of Death, disarmed by the amiable treatment accorded to him, himself went before the throne of God and presented the young wife's petition. The end was God added seventy years to the life of Rabbi Reuben's son.
