Revelation 10:3-8
10:3 Then he shouted in a loud voice like a lion roaring, and when he shouted, the seven thunders sounded their voices.
10:4 When the seven thunders spoke, I was preparing to write, but just then I heard a voice from heaven say, “Seal up what the seven thunders spoke and do not write it down.”
10:5 Then the angel I saw standing on the sea and on the land raised his right hand to heaven
10:6 and swore by the one who lives forever and ever, who created heaven and what is in it, and the earth and what is in it, and the sea and what is in it, “There will be no more delay!
10:7 But in the days when the seventh angel is about to blow his trumpet, the mystery of God is completed, just as he has proclaimed to his servants the prophets.”
10:8 Then the voice I had heard from heaven began to speak to me again, “Go and take the open scroll in the hand of the angel who is standing on the sea and on the land.”
