Revelation 14:3 - Matthew Poole's English Annotations on the Holy Bible

And they sung as it were a new song before the throne: by the throne here is meant the throne of God in glory. The new song here spoken of, is probably the same with that we met with before, Revelation 5:11,12, sang by the voice of many angels round about the throne and the beasts and the elders: called new, either for the excellency of it; or, because sung unto God after Christ was manifested in the flesh; the design of it was to declare the worthiness of Christ to receive power, and riches, and wisdom, and strength, and honour, and glory, and blessing: see Revelation 5:12. Mr. Mede saith thus of it; "If God shall at any time make me fully to understand it, I will happily more largely explain it, for it is deeply settled in my mind, that the whole mystery of evangelical worship is in it contained." And quite through the Scripture generally, a new song signifies a song which praiseth God for some new benefits received from him. And before the four beasts, and the elders; the throne, beasts, and elders, described before, Revelation 4:1-11, And no man could learn that song but the hundred and forty and four thousand, which were redeemed from the earth: during the reign of antichrist none could learn this new song, viz. to give glory to Jesus Christ alone, ascribing to him power, riches, wisdom, strength, honour, glory, and blessing; but a small number redeemed through the blood of Christ, from that vain conversation received by tradition from their fathers, 1 Peter 1:18. All the other part of the world gave Christ's honour and glory to the virgin Mary, angels, and saints, &c.
