In 1582, in Edinburgh, an imprisoned minister named John Durie was released from prison. He was welcomed on the edge of town by several hundred of his friends, and as they walked along, that number soon swelled to several thousand. Someone began to sing—Psalm 124—and they all, much moved, sang it together in four parts. “Let Israel now say in thankfulness…” One of the chief persecutors was said to have been more alarmed by this spectacle than anything else he had seen in Scotland, which is very likely saying something.
