The Treasury of David is a commentary on the Book of Psalms in the Old Testament of the Bible. It is by Charles Haddon Spurgeon who is called â€śthe Prince of Preachersâ€ť and one of the greatest Christian writers of his time. This work was first published in weekly installments over the period of 21 years in the London Metropolitan Tabernacle's periodical "The Sword and the Trowel" by Charles Haddon Spurgeon. Sections were released in volumes until the seventh and final volume was published in 1885. In this volume you have the entire seven volumes along with the text of the Psalms that you are studying. Other versions on Amazon only give you one or two volumes. This is the entire set. Spurgeon's wife, said of the volume "If he had never written any other work this would be his permanent legacy. This has a linked Table of Contents and active links within each of the Psalms for easy movement around the text.
