And the angel whom I saw standing on the sea and on the land lifted up his right hand to heaven, ⁶and swore by Him who lives forever and ever, who created heaven and the things in it, and the earth and the things in it, and the sea and the things in it, that there shall be delay no longer, ⁷but in the days of the voice of the seventh angel, when he is about to sound, then the mystery of God is finished, as He preached* to His servants the prophets.

(ASV)

And when the seven thunders had uttered their voices, I was about to write: and I heard a voice from heaven saying unto me, Seal up those things which the seven thunders uttered, and write them not. 5And the angel which I saw stand upon the sea and upon the earth lifted up his hand to heaven, 6And sware by him that liveth for ever and ever, who created heaven, and the things that therein are, and the earth, and the things that therein are, and the sea, and the things which are therein, that there should be time no longer: 7But in the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as he hath declared to his servants the prophets.
