The Holy Bible, OT Book of Psalms, is based upon the work of the American King James Version of the Bible. The AKJV Bible has updated the 17th century word usage found in the Authorized King James Version by clarifying the Old English word endings. All AKJV Yehovah editions avoid translation and language interpretations created by Jerome and by Westcott & Hort. OT Book of Psalms contains additional bonus study materials and outlines that can help foster a deeper understanding of the ancient writings inspired by Yehovah.
