GILUY MILTA B'ALMA: A new Midrash (to Jeremiah 23-24)? It is from the Cambridge Cairo Geniza collection, possibly donated by Rabbi Solomon Aaron Wertheimer; it consists of five leaves written in an Oriental script; its beginning is lost but it relates to these chapters of Jeremiah; and it has linguistic similarities to the classical Midrashim and the Jerusalem Talmud.
