Revelation 10:5-7

5The angel whom I saw standing on the sea and on the land raised his right hand to heaven.

6He swore an oath by the one who lives forever and ever, who created heaven and everything in it, the earth and everything in it, and the sea and everything in it. He said, “There will be no more delay.

7In the days when the seventh angel is ready to blow his trumpet, the mystery of God will be completed, as he had made this Good News known to his servants, the prophets.”
