He wandered through Galicia, Poland, and Russia with his family as an itinerant scholar, supporting himself financially by working as a teacher, proofreader, merchant, scribe, cantor, and preacher.
In 1804, Feder published Lahat ha-ḥerev, an attack on modern Biblical criticism directed against Aaron Wolfssohn and Isaac Satanov.
[3] The same year he released Mevasser tov, an introduction to Hebrew grammar with a criticism of the Masorah commentary Menorat Shlomo, by Rabbi Phoebus of Dubrovno.
Feder also wrote Kol meḥatzetzim ('Voice of the Archers', 1813), a bitter satire against Menachem Mendel Lefin for his Yiddish translation of the Book of Proverbs.
Additional works by Feder were published after his death, including a rhymed play entitled Adam ve-Ḥavah ('Adam and Eve'), the Zohar ḥadash le-Purim, a humorous parody for Purim in Aramaic, and Shem u-she'erit, a volume of literary epistles and poems.
