These sages did not say anything about themselves or their wisdom. The captain sold Rabbi Shemariah in Alexandria of Egypt; the latter went up to Cairo, where he became head of a school; Rabbi Hushiel was sold on the coast of Africa, whence he went up to the city of Kairuwan, which in those days was the mightiest of all Ishmaelitish cities in the land of Maghrib. There Rabbi Hushiel became head of a school, and there he begot Rabbi Hananel his son. Then the captain went to Cordova, where he sold Rabbi Moses and Rabbi Enoch his son. They were redeemed by the men of Cordova, who were not aware of the great learning of the captives. There was in Cordova a synagogue that was called the Synagogue of the House of Study, and there was a judge named Rabbi Nathan, who was exceedingly pious. The people of Spain, however, were not well-versed in the words of our teachers of blessed memory. Nevertheless, with the little knowledge that they possessed, they arranged discussions, interpretations, and arguments. Once Rabbi Nathan the judge interpreted the law that an ablution is required for each sprinkling, which occurs in the tractate Yoma, and they were not able to explain it. Whereupon Rabbi Moses, who sat in a corner like a beadle, stood up before Rabbi Nathan, and said to him: ‘My master, there would be too many ablutions.’ When he and his pupils heard his words, they marvelled one with the other, and asked him to explain the law to them; whereupon he explained the law in the right manner. They then asked him to explain all their difficulties, and they set forth their questions, which he answered with the abundance of his wisdom. There were litigants outside the House of Study who were not permitted to enter until the pupils had finished their lesson. On that day Rabbi Nathan the judge came out, and the litigants went after him. But he said to them: ‘I am no longer judge; but this man, who is clad in sackcloth and is a stranger, is my teacher and master, and I am his pupil from to-day and henceforth. Now appoint ye him judge in the congregation of Cordova.’ And they did so. The congregation gave him a good allowance, and presented him with costly garments and a carriage. The captain then wanted to cancel his sale, but the king would not permit him, for he rejoiced with great joy when he heard that the Jews of his kingdom no longer needed the men of Babylon. When the report thereof was heard in all the land of Spain and the land Maghrib, all the pupils came to study under Rabbi Moses, and all the questions that formerly had been addressed to the academies were directed to him. This took place in the days of Sherira Gaon, approximately about the year four thousand seven hundred and fifty.
