In Verse 13 of Chapter 11 or Revelation, in a display of His power and judgement, God shakes Jerusalem with a devastating earthquake, when He resurrects and snatches His two witnesses away into heaven.

God never lets sin go unchecked. Many times He prolongs judgement, but at other times He judges sin immediately. In the case of the unbelieving world’s treatment of His witnesses and their subsequent celebration after their murder, God's judgement falls immediately.

This earthquake levels one tenth of Jerusalem and immediately snuffs out the lives of seven thousand people.
