Revelation 10:2-3

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]
