The Psalms is a devotional commentary on each of the 150 psalms. Originally written in German under the title Psalmen, this commentary is the product of passionate writing and dedicated translating. For professional readers, this book serves as a great source of ideas for teaching and preaching God's Word.
This is truly what its subtitle describes - a "Devotional Commentary". I recommend its use for one's personal devotional purposes. It's a solid, confessional Lutheran commentary on the Psalms written in a style that both pastor and layperson can appreciate.
