Renowned in his times and for posterity for his genius and exceptional sharpness (several generations later, when a Torah scholar would say a profound and sharp pilpul, he would be told that his words are enlightening like the Machaneh Levi – see: Ohalim, Chiddushei Maharil Diskin UVeno R. Yitzchak Yerucham, Jerusalem, 2001, note on p. 215). He corresponded with the great Torah leaders of his times, such as R. Akiva Eger and his brother-in-law R.

His books include Machaneh Levi on the Talmud (Offenbach, 1801); Lachmei Todah – novellae on Halachah and Aggadah (Offenbach, 1816); and Responsa Chomer BaKodesh (Zhovkva, 1876).
