Eliakim Getzel ben Judah ha-Milzahgi[note 1] (Hebrew: אליקים גצל בן יהודה המילזאהגי; c. 1780, Smiela – 17 July 1854, Brody), also known by the acronym Rabiyah (ראבי״ה), was a Polish-born Talmudist.
Eliakim Getzel ha-Milzahgi was born in the Polish town of Smiela into a prominent rabbinical family that included scholars Ephraim Zalman Margolioth and Jacob of Lissa.
[3] He worked as the rabbi of a small town, and later as a teacher and merchant in Lemberg and Brody,[3] all while pursuing Jewish scholarship under the patronage of Berish Blumenfeld.
The only published book of his was Sefer Rabiyah (Ofen, 1837), a criticism of Leopold Zunz's Die gottesdienstlichen Vorträgeder Juden: historisch entwickelt and of Solomon Judah Loeb Rapoport's biography of Eleazar ben Kalir.
[4] He published in the Jewish press a denunciation of the alleged forgeries of Abraham Firkovich, and, in his essay Mirkevet Esh, he argued in favour of permitting train travel on the Sabbath.
