The Revelation 5:8-9

When He had taken the scroll, the four living creatures and the twenty-four elders fell down before the Lamb, each holding a harp and golden bowls full of incense—which are the prayers of the kedoshim. And they are singing a new song, saying, “You are worthy to take the scroll and to open its seals. For You were slain, and by Your blood You redeemed for God those from every tribe and tongue and people and nation.
