Rev. 15. 3. _They sing the Song of Moses, the Servant of God, and the Song of the Lamb_; that is, a Song for temporal and for spiritual Deliverances; or, a Song for all antient or all later Salvations of the Church. As Moses was a Redeemer from the House of Bondage, and a Teacher of Divine Worship with Harps and Ceremonies; so the Lamb is a Redeemer from _Babylon_ and spiritual Slavery, and he {240} is the great Prophet to teach his Church the spiritual Worship of the Gospel. The Church now, under the Salvations and Instructions of the Lamb, sings with the Voice to the Glory of the Vengeance and the Grace of God, as _Israel_ under the Conduct of _Moses_ sung with Harps; for we must observe, that these Visions of the Apostle _John_ often represent Divine Things in a Gospel-Church, in Imitation of the Ranks and Orders of the _Jewish_ Camp and Tribes, and by the Rites and Figures used in the time of _Moses_; and it would be as unreasonable to prove from this Text, that we must sing the very words of the _15th of Exodus_ in a Christian Church, as to prove from this Book of the _Revelations_ that we must use Harps and Altars, Censers, Fire and Incense. But 'tis plain that the _15th of Exodus_ cannot be here intended, because the Words of the Song are mention'd just after, (viz.) _Great, and marvellous are thy Works, Lord God Almighty, just and true are thy Ways, thou King of Saints_. Yet after all, if it could be proved, that the very Song which _Moses_ sung is here design'd, still it must be confest that the Song of the Lamb is also to be sung; and if the following Words in this Text are not to be esteem'd the Song of _Moses_, then neither are they to be esteem'd the Song of the Lamb; because there is not any express mention of the Lamb, or his Death, or Resurrection, or Redemption; nor is there any other Song in Scripture that bears that title and consequently it must signifie a Song compos'd {241} to the praise of God for our deliverance by the Lamb, in imitation of the Joy composed for deliverance by the Hand of _Moses_: And thus at least we are to suit part of our Psalmody to the Gospel-State as well as borrow part from the Old Testament, which is the chief point I designed to prove. The next Enquiry then proceeds thus: How must the Psalms of _David_ and other Songs borrowed from Scripture, be translated in order to be sung in Christian Worship? Surely, it will be granted, that to prepare them for Psalmody under the Gospel, requires another sort of Management in the Translation, than to prepare them merely for Reading as the _Word of God_ in our Language, and that upon these two accounts:
