Complete Commentary on the Whole Bible, by Matthew Henry, at sacred-texts.com
The name of this book signifies "The Preacher." The wisdom of God here preaches to us, speaking by Solomon, who it is evident was the author. At the close of his life, being made sensible of his sin and folly, he recorded here his experience for the benefit of others, as the book of his repentance; and he pronounced all earthly good to be "vanity and vexation of spirit." It convinces us of the vanity of the world, and that it cannot make us happy; of the vileness of sin, and its certain tendency to make us miserable. It shows that no created good can satisfy the soul, and that happiness is to be found in God alone; and this doctrine must, under the blessed Spirit's teaching, lead the heart to Christ Jesus.
