Revelation 10:5-7

Darby Translation

⁵ And the angel whom I saw stand on the sea and on the earth lifted up his right hand to the heaven,

⁶ and swore by him that lives to the ages of ages, who created the heaven and the things that are in it, and the earth and the things that are in it, and the sea and the things that are in it, that there should be no longer delay;

⁷ but in the days of the voice of the seventh angel, when he is about to sound the trumpet, the mystery of God also shall be completed, as he has made known the glad tidings to his own bondmen the prophets.
