Revelation 10:1-3

1I saw another powerful angel come down from heaven. He was dressed in a cloud, and there was a rainbow over his head. His face was like the sun, and his feet were like columns of fire.

2He held a small, opened scroll in his hand. He set his right foot on the sea and his left on the land.

3Then he shouted in a loud voice as a lion roars. When he shouted, the seven thunders spoke with voices of their own.
