Prophetic Psalms in their Relation to Israel by Benjamin Wills Newton and published by Classics.
The Psalms may be regarded as God's own commentary on the things recorded in other parts of His Holy Word. In other part of Scripture He has revealed the events which have or shall under His appointment come to pass on the earth. In the Psalms we find descriptions adapted to those events - descriptions not unfrequently supplied by the words of supplication or of thanksgiving employed by those who are personally acting in these circumstances. - Opening words of the Book.
