The 150 Psalms of the Old Testament span a timeframe of 873 years, from oldest to newest—the newest of which was written nearly three thousand years ago. Despite the incredible time gap between the writings of these songs and our current day, they are still incredibly relevant to the contemporary life. Theologian William S. Plumer notes this in the introduction to Studies in the Book of Psalms, then penned over 1,000 pages of profound insight into this ancient Old Testament literature. His elucidations provide an excellent backdrop to the study of the Psalms.
