I esteem the Book of _Psalms_ the most valuable Part of the Old Testament upon many Accounts: I advise the Reading and Meditation of it more frequently than any single Book of Scripture; and what I advise I practise. Nothing is more proper to furnish our Souls with devout Thoughts, and lead us into a World of Spiritual Experiences: The Expressions of it that are not _Jewish_ or peculiar, give us constant Assistance in Prayer and in Praise: But yet if we would prepare _David_'s Psalms to be sung by Christian Lips, we should, observe these two plain Rules. _First_, They ought to be translated its such a Manner as we have reason to believe _David_ would have compos'd 'em if he had lived in our Day: And therefore his Poems are given as a Pattern to be imitated in our Composures, rather than as the precise and invariable Matter of our Psalmody. 'Tis one of the Excellencies of Scripture-Songs, that they {253} are exactly suited to the very Purpose and Design for which they were written, and that both in the Matter, in the Stile, and in all their Ornaments: This gives Life and Strength to the Expression, it presents Objects to the Ears and to the Eyes, and touches the Heart in the most affecting Manner. _David_'s Language is adapted to his own Devotion, and to the Worship of the _Jewish_ Church; he mentions the very Places of his Journies, or Retirements, of his Sorrows, or his Successes; He names the Nations that were Enemies of the Church, or that shall be its Friends and tho for the most part he leaves the single Persons of his Time nameless in the Body of his Psalm, yet he describes them there with great Particularity, and often names them in the Title. This gives us abundant Ground to infer, that should the _Sweet-Singer of Israel_ return from the Dead into our Age, he would not sing the Words of his own Psalms without considerable Alteration; and were he now to transcribe them, he would make them speak the present Circumstances of the Church, and that in the Language of the New Testament: He would see frequent Occasion to insert the Cross of Christ in his Song, and often interline the Confessions of his Sins with the Blood of the Lamb; often would he describe the Glories and the Triumphs of our blessed Lord in long and flowing Verse, even as St. _Paul_, when he mentions the Name and Honours of Christ can hardly part his Lips from 'em again: {254} His Expressions would run ever bright and clear; such as here and there we find in a single Verse of his old Composures, when he is transported beyond himself, and carried far away from _Jewish_ Shadows by the Spirit of Prophecy and the Gospel. We have the more abundant Reason to believe this, if we observe, that all along the sacred History as the Revelations of God and his Grace were made plainer, so the Songs of the Saints express'd that Grace and those Revelations according to the Measure of their Clearness and Increase. Let us begin at the Song of _Moses_, Exod. 15. and proceed to _David_
