Revelation 5:2; Revelation 5:5; Revelation 5:9

2 And I saw a mighty angel proclaiming in a loud voice, “Who is worthy to break the seals and open the scroll?”

5 Then one of the elders said to me, “Do not weep! See, the Lion of the tribe of Judah, the Root of David, has triumphed. He is able to open the scroll and its seven seals.”

9 And they sang a new song, saying: “You are worthy to take the scroll and to open its seals, because you were slain, and with your blood you purchased for God persons from every tribe and language and people and nation.
