Sahal's attacks upon the Rabbanites were too offensive to remain unanswered. An influential Rabbanite seems to have forced him into silence by aid of the government. Saadiah's pupil, Jacob ben Samuel, stung to the quick by the abuse which Sahal and other Karaites had heaped upon his master, took up the cudgels in his behalf. He delivered speeches in the streets and in the public places against Karaism and the proselytizer Sahal. The latter, however, did not remain silent. In a passionate letter to Jacob, written in beautiful Hebrew, he continued his attacks, and gave a faithful picture of the state of Karaism and Rabbanism in his time, leaving out neither the light nor the shade of both sides. After the versified attack and the reproaches for Jacob's incorrect Hebrew and the injury done to Judaism by the Rabbanites, Sahal proceeds: I am come from Jerusalem in order to warn the people, and to bring them back to the fear of God. Would that I had the power of going from town to town to awaken the people of the Lord. You think that I came here for the sake of gain, as others come who grind the faces of the poor; but I came in the name of God, in order to bring back the thoughts of the people to true piety, and to warn them not to rely on human institutions, nor to listen to the sayings of the two evil women (the Gaonic schools). How shall I not do it, since my heart is moved by the irreligion of my brethren, who are walking in the wrong path, who impose a heavy yoke upon the ignorant people, who oppress them and rule over them through excommunication and persecution, who call to their aid the power of the Mahometan officials, who compel the poor to borrow money on interest, in order to benefit by it and to be able to bribe the officials? They feed themselves, but not their flocks, and they do not teach the word of God in the proper way. If any one asks them the reason for anything they do, they antagonize him. Far be it from me that I should be silent, when I see that the leaders of the community, who say that they constitute the Synhedrion, eat without compunction with non-Jews. How shall I be silent, when I perceive that many of my people make use of idolatrous practices? They sit on the graves of the departed and invoke the dead, and pray to Rabbi José the Galilean, saying, "O heal me, and make me fruitful." They make pilgrimages to the shrines of the pious dead, light candles there, and burn incense. They also make vows that they may be cured of their diseases. O that I had the power to go everywhere and to proclaim it aloud, to admonish men in the name of the Lord, and to deter them from their evil course. And now, O House of Israel, have mercy on your souls, and choose the right path. Do not object and say that the Karaites, too, differ among themselves as regards
