Revelation 10:5-7

New Catholic Bible

⁵ Then the angel whom I had seen standing on the sea and on the land raised his right hand to heaven ⁶ and swore by him who lives forever and ever and who created heaven and earth and the sea and everything that is in them: “There will be no further delay. ⁷ When the time comes for the seventh angel to sound his trumpet, the mysterious purpose of God^[a] will be fulfilled, just as he announced to his servants the Prophets.”
