A "Psalter/Commentary" combining in-depth study of Psalms 42-89 with over a hundred new songs based on the text of these psalms. This volume, encompassing Psalms 42-89 (books two and three of the book of Psalms), is the second of three projected volumes. Volume one covered book one of Psalms (1-41), and volume three will incorporate books four and five of the Psalter (90-150). The intent of this series is not to produce technical volumes. rather, they are intended for use by church leaders, ministers, informed lay persons, and bible teachers to obtain basic understanding of some of the concerns and issues found in a particular Psalm, and go from there to an application of the Psalm for present-day worship in song. For each psalm there is a translation, treatment of its structure and theology, and then two to four musical settings: a "traditional" hymn setting and a "contemporary" setting and sometimes also a verbatim chant. This variety demonstrates several ways of bringing the Psalms into Christian worship. Most of the music in timeless is intended for congregational singing. Timeless is an ecumenical and international project. While having its origin in the a cappella tradition of Churches of Christ, the book is based on the conviction that all Christian communions share the original hymnbook of the second temple and the church. The editor, therefore, has solicited commentaries, compositions, and lyrics from a broad range of Christian traditions.
