Revelation 5:9-10

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]
