Revelation 5:8-10

And when He had taken the scroll, the four living creatures and the twenty-four elders fell down before the Lamb (Christ), each one holding a harp and golden bowls full of fragrant incense, which are the prayers of the saints (God’s people). And they sang a new song [of glorious redemption], saying, “Worthy and deserving are You to take the scroll and to break its seals; for You were slain (sacrificed), and with Your blood You purchased people for God from every tribe and language and people and nation. [Ps 33:3] “You have made them to be a kingdom [of royal subjects] and priests to our God; and they will reign on the earth.” [Ex 19:6; Is 61:6; Rev 20:6]
