Commentary on the Prophets and Writings (Nach) written by Rabbi David Altschuler in the 18th century. It is primarily based on the commentary of Radak, but also draws on other sources. After Rabbi David Altschuler’s death, his works were completed by his son, Rabbi Hillel Altschuler, who instituted the division of the commentary into two parts. Known collectively as "Metzudot", Metzudat Tzion explains unfamiliar and difficult words found in the text, while Metzudat David delves into the meaning of the text.
