Learned and pious man left son, Rabbi Isaac, more learned and pious than himself and a Dayyan. The dead man appeared to his son in a dream on the Eve of New Year and ordered him to be converted next day. He was troubled, put on sackcloth and fasted three days. On Eve of Kippur, the father again appeared, and reproved him for not obeying. The son argued. Father again told him to convert himself the next day (Kippur). He did not sleep and wept all next day. Congregation noticed it and asked him the reason. After long persuasion he told them that he had decided to become converted. Congregation wept, as there would be no one left to speak for them and defend them. They fasted and wept. Rabbi Isaac went to the king, and said he would be converted on condition that he could return to his own religion when ever he chose. The king consented. The king was very old. There was a mighty prince whose three sons strangled the king’s only son, who was heir to the throne. The Jews were accused of the murder. Rabbi Isaac proved to the king at the cemetry who the murderers were by making the
dead son himself tell it. The murderers were slain in consequence. Rabbi Isaac returned to Judaism as a great rabbi with mighty honour.
