'Roaring of a Lion' in the Bible

The roaring of a lion, And the voice of a fierce lion, And teeth of young lions have been broken.

The king's wrath is as the roaring of a lion; but his favour is as dew upon the grass.

The fear of a king is as the roaring of a lion: whoso provoketh him to anger sinneth against his own soul.

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].
