This commentary on the Psalms by Ernst Wilhelm Hengstenberg, a 19th century German Lutheran theologian and exegete, is still widely known and cited and is considered a solid addition to the personal library of any serious student of the Old Testament.
Hengstenberg is cited hundreds of times in works such as Pulpit Commentary and Keil & Delitzsch Commentary on the OT. The translator and editor of Calvin's Commentaries also makes frequent reference to the works of this 19th century German Protestant commentator.
