Revelation 10:1-3

1Then I saw another mighty angel coming down from heaven, surrounded by a cloud, with a rainbow over his head. His face shone like the sun, and his feet were like pillars of fire.

2And in his hand was a small scroll that had been opened. He stood with his right foot on the sea and his left foot on the land.

3And he gave a great shout like the roar of a lion. And when he shouted, the seven thunders answered.
