Revelation 5:9

“And they sung a new song, etc.] Upon a new occasion and subject, redemption by the blood of the Lamb, and his worthiness to open the sealed book; and in distinction from the old song of Moses and the children of Israel at the Red sea; and this was a most famous and excellent song, an unheard of one, and which none could learn, or sing, but the redeemed of the Lamb: saying, thou art worthy to take the book, and open the seals thereof.

“5:9-10 The whole created order joins in a new song of praise to the Lamb (cp. 14:1-5; Ps 149:1; Isa 42:10). • The Lamb is worthy because, through his sacrifice, he won the right to break the seals of the scroll and enact God’s purposes in history. • The song summarizes the implications of the Good News about Jesus (1 Pet 1:18-25).”
