Revelation 5:2-3

5:2 And I saw a powerful angel proclaiming in a loud voice: “Who is worthy to open the scroll and to break its seals?” 5:3 But ¹  no one in heaven or on earth or under the earth was able to open the scroll or look into it.

Revelation 4:11

4:11 “You are worthy, our Lord and God,

to receive glory and honor and power,

since you created all things,

and because of your will they existed and were created!” ² 

[5:3]  ¹ tn Here καί (kai) has been translated as “but” to indicate the contrast present in this context.

[4:11]  ² tc The past tense of “they existed” (ἦσαν, hsan) and the order of the expression “they existed and were created” seems backwards both logically and chronologically. The text as it stands is the more difficult reading and seems to have given rise to codex A omitting the final “they were created,” 2329 replacing “they existed” (ἦσαν) with “have come into being” (ἐγένοντο, egeneto), and 046 adding οὐκ (ouk, “not”) before ἦσαν (“they did not exist, [but were created]”). Several mss (1854 2050 Ï^A sa) also attempt to alleviate the problem by replacing ἦσαν with “they are” (εἰσιν, eisin).
