Revelation 10:5-7

And the angel that I saw standing upon the sea and upon the earth lifted up his right hand to heaven, and sware by him that liveth for ever and ever, who created the heaven and the things that are therein, and the earth and the things that are therein, and the sea and the things that are therein, that there shall be delay no longer: but in the days of the voice of the seventh angel, when he is about to sound, then is finished the mystery of God, according to the good tidings which he declared to his servants the prophets.
