As we wait for the opening of the 6th and 7th Seal, what will occur after the first rapture that is according to readiness is Rev. 8: "And when he had opened the seventh seal, there was silence in heaven about the space of half an hour" (v.1).

This "half an hour" or 'half a time' could foreshadow the first half of the 7 year Tribulation. Therefore, the first four Trumpets are the first 42 months or 42 x 30 = 1260 days.

Then during the Great Tribulation (2nd half) when the armies of the world surround Jerusalem it will be amazing because the Two Witnesses after thousands of years will be back declaring to the world this evil doing. Imagine listening to Enoch and Elijah speak and watching them conduct themselves before men. The hold great authority. These are the only two individuals in the history of the Scriptures who did not die but were raptured alive. We are appointed once to die.
