ntators have written on the Psalms, it has long been difficult to find a comprehensive treatment of this book of Scripture in one volume. Some expositions have excelled in scholarship, but, unlike the Psalter, in instructing the mind they have failed to exercise the heart. Dr Plumer's Commentary avoids this defect, the author believing that from the Psalms 'piety has derived more nourishment than from any other source,' and that his work should serve that same purpose. In 1211 pages he gives both exposition and doctrinal and practical remarks and presents in readable form a great wealth of material drawn from all the leading commentators who had gone before him. In the opinion of Dr John Macleod of Edinburgh, he succeeded in producing the best single volume on this book of Scripture.
