Aharon Roth or Aaron Rote (Hebrew: אהרן ראטה) known as Reb Arele (1894−1947), was a Hungarian Hasidic rebbe and Talmudic scholar. He first established a Hasidic community he called Shomer Emunim (Guardian of Faith) in the 1920s in Satu Mare and in the 1930s in Berehovo, before he settled in Jerusalem, where he also founded a Hasidic community of the same name. His main work is the two-volume Shomer Emunim, written in 1942 in reaction to the news about the Nazi atrocities in Eastern Europe.
