Later he escaped to Turkey, probably to Adrianople, where he wrote the "Shebeṭ Yehudah" ("Shevet Yehudah") an account of the persecutions of the Jews in different countries and epochs. In a short preface he says that he found an account of some persecutions at the end of a work of Judah ibn Verga, which he copied; to this he added a narration of the persecutions of his own time, the compilation being afterward completed and edited by his son, Joseph ibn Verga. The title ""Shebeṭ Yehudah"", which is an allusion to Judah ibn Verga (""shebeṭ"" in Hebrew being the equivalent of the Spanish "verga", "staff"), refers to Gen. 49:10.
