Revelation 10:1-3

Then I saw another mighty angel coming down from heaven, clothed in a cloud, with a rainbow (halo) over his head; and his face was like the sun, and his feet (legs) were like columns of fire; [Ex 13:21, 22; Ezek 1:26-28; Dan 7:13; Matt 17:2] and he had a little book (scroll) open in his hand. He set his right foot on the sea and his left foot on the land; [Ezek 2:9; Hos 11:10] and he shouted with a loud voice, like the roaring of a lion [compelling attention and inspiring awe]; and when he had shouted out, the seven peals of thunder spoke with their own voices [uttering their message in distinct words]. [Ps 29]
