He led the less radical sect of Peshischa for two years, until his death in 1829, after which his followers adopted R. Israel Yitzhak Kalish of Vurka as his successor.

At first, R. Avraham Moshe refused the position to avoid a schism in the community, but after much pressure from his father's followers he agreed.

Ultimately R. Avraham Moshe's died only two year later during the seventh night of Hanukkah in 1828 in the town of Biała Rawska (where he is buried), on his way from Warsaw to Przysucha.
