MORDECAI BEN JUDAH (MORDUSCH):
Polish ritualist; lived at Lamkumsh; died 1584. He edited the Maḥzor with the commentary of Abraham Abigdor, to which he added notes of his own (Lublin, 1567); in the same way he edited the latter's seliḥot (Cracow, 1584). Two other editions of the seliḥot appeared, revised and enlarged by his son-in-law Hirsch Sundels (Prague, 1587, and Lublin, 1643).
