Asher Zebi of Ostrowo

Asher Zebi ben David of Ostrowo was a 19th-century hasidic rabbi who served as Av Beit Din of Korets, Volhynia, and later as "maggid" (preacher) of Ostrowo, in the government of Lomza in Russian Poland. He was a pupil of Rabbi Dov Ber of Mezeritch. Eliezer Zweifel in his work in defense of Hasidism ("Shalom al-Yisrael," pp. 81, 82) quotes aphorisms from this work; one of which shows Asher's contempt for those who study the laws of nature or secular science.
