Revelation 10:2-7

He had a little book open in his hand. And he set his right foot on the sea and his left foot on the land, and cried with a loud voice, as when a lion roars. When he cried out, seven thunders uttered their voices. Now when the seven thunders uttered their voices, I was about to write; but I heard a voice from heaven saying to me, “Seal up the things which the seven thunders uttered, and do not write them.” The angel whom I saw standing on the sea and on the land raised up his hand to heaven and swore by Him who lives forever and ever, who created heaven and the things that are in it, the earth and the things that are in it, and the sea and the things that are in it, that there should be delay no longer, but in the days of the sounding of the seventh angel, when he is about to sound, the mystery of God would be finished, as He declared to His servants the prophets.
