Some Help from Marty

Though I haven't picked one up yet, this looks to be a helpful resource from Concordia Publishing House. It's Reading the Psalms with Luther: The Psalter for Individual & Family Devotions with Introductions by Martin Luther. They run about $14.99 at Amazon & here in St. Louis at the Concordia Bookstore.

What you get is the entire Psalter (ESV) with short introduction/commentary from Luther at the head of each psalm. In all of Luther's many writings on the psalms, the only work that he produced which commented on all 150 Psalms was entitled The Summaries of the Psalms (pub. 1532). Those summaries appear here in this new volume. As well Luther "assigns each psalm to one of the Ten Commandments and to one of the petitions from the Lord's prayer, he says that the psalms 'belong to,' 'flow from,' even are in' these petitions and commandments" (from the Preface, p. 4). There is also a schedule for praying through the Psalter regularly, and I believe the entire Psalter is pointed for chanting and includes the chants from the new Lutheran Service Book.
