Rabbi David Altschuler of Prague (1687-1769) was a biblical commentator and the author of a classic commentary, known as the Metzudot, to the Hebrew Bible's Nevi'im and Ketuvim.
R. Altschuler saw that the study of Tanakh, Hebrew Bible, had become weak among European Jews and even among scholars.
According to the Hida, these sources include Rashi, Ibn Ezra, Ralbag, Moshe Alshich, Saadiah Gaon and Ramban.
David's son Yechiel Hillel Altschuler also served as rabbi of Yavoriv, and finished his father's great work, and traveled extensively in Europe in order to publish and spread it.
In time the Metzudot became one of the basic commentaries on Neviim and Ketuvim, printed in most editions of the Hebrew Bible with commentators.
