Dhu Nuwas
In the 6th century Tiberias was still the seat of Jewish religious learning. In light of this, a letter of Syriac bishop Simeon of Beth Arsham urged the Christians of Palaestina to seize the leaders of Judaism in Tiberias, to put them to the rack, and to compel them to command the Jewish king, Dhu Nuwas, to desist from persecuting the Christians in Najran.
