Revelation 10:1-7

Then I saw another extremely powerful messenger coming out of heaven, robed in a cloud. There was a halo over his head like a rainbow; his face shined bright like the sun, and his legs like pillars of fire. He held an opened scroll in his hand. He set his right foot on the sea and his left foot on the land and gave a tremendous shout, like a lion’s roar. When he shouted, the seven thunders responded, rumbling out their messages. I was about to write the messages of the seven thunders, but I heard a heavenly voice say to me: Don’t write a word, but place a seal on what the seven thunders have spoken. Then the mighty angel whom I saw astride the sea and the land raised his right hand to heaven and swore an oath by him who lives for an eternity of eternities, the Creator of heaven and earth and sea and all that is in them: No more delay! For in the day when the seventh angel is to sound his trumpet, the mystery of God will be fulfilled, just as he announced to his servants the prophets.
