7. A great voice as a lion roareth: The Lamb in the midst of the throne, once slain, who was the Lion of the tribe of Judah, who had conquered to open the book and loose its seals, now came as the “ mighty angel” to announce the near end of the things in the book; and when his “ loud voice” heralded the angel’ s proclamation, seven thunders uttered their voices, as signs of revolutionary events that would presage the end. Thunder was regarded as the voice of God. (Job 37:2; Psalms 18:13; Psalms 81:7; Isaiah 30:31-32) Thunder attended the inauguration of the law. (Exodus 19:16) When the people heard God’ s voice, they said it thundered. (John 12:29) It was a symbol of divine power in the executions of vengeance on evil-doers. (2 Samuel 2:10; 2 Samuel 22:14; Isaiah 29:6) And that was its significance here.
