”"Allan Harman's commentary is the fruit of a lifetime's study of the Psalter and provides a well-informed, reliable guide to the vast literature on the subject. The extensive introduction is itself worth its weight in gold while the Scripture text is opened up in a clear, careful and devout way."“Philip H. Eveson(Former principal of London Theological Seminary)”"The focus is on the original meaning of the psalms with clear explanations of the message of each psalm through an analsysis of structure, key words, and the flow of the psalm. And yet, the meaning of the psalms for God's people today is also emphasized by showing important connections to the New Testament. The reader will discover the rich treasures in the Psalms through the use of this commentary."“Richard P. Belcher, Jr.(John D. and Frances M. Gwin Professor of Old Testament and Academic Dean, Reformed Theological Seminary, Charlotte, North Carolina)”"This commentary will be a worthy resource for the pastor and student in the study as well as the layman seeking personal edification."“Michael Lefebvre(Pastor, Christ Church Reformed Presbyterian Church, Indianapolis, Indiana)”... highly recommended, deserving a place in every preacher's library and in every Christian home.“Reformed Theological Review
