The Scottish Psalter (1650) is a landmark translation of the Book of Psalms in common meter, authorized by the Church of Scotland. During times of severe religious persecution, Covenanters sang these metrical psalms in secret outdoor gatherings on stormy hillsides. The Covenanters drew immense courage from singing God's Word directly, and classics like 'The Lord's My Shepherd' (Psalm 23) became anthems of resistance and absolute trust in the face of death, shaping the spiritual fabric of Scotland and the global church for centuries.
