We call this book ordinarily, “The Psalms of David,” but David did not write them all. A great many of them were written by other people. They were the Psalms of David in the sense that we call the old gospel humn book, “The Moody and Sankey Hymn Book.” Moody did not write any of the hymns and Sankey only a sprinkling of them, but these men compiled the book. If you go over to Great Britian today you can go to the original publishers of it and say, “I would like to have a copy of the Moody and Sankey Hymn Book,” and they will hand you a book with twelve hundren hymns in it. In the old days this book had only six hundred hymns. It was compiled by them originally, but a great many others have been added from time to time, and today there is this vast collection. We can think of the book of the Psalms of David in the same way.
