In Revelation 8:6 we read,
Then the seven angels who had the seven trumpets prepared to sound them.
The first angel sounded his trumpet, and after this in v.7 we read,
A third of the earth was burned up, a third of the trees were burned up and all the green grass was burned up.
In 9:3-4, after the fifth angel has sounded his trumpet we read,
And out of the smoke locusts came down upon the earth and were given power like that of scorpions of the earth. They were told not to harm the grass of the earth or any plant or tree, but only those people who did not have the seal of God on their foreheads.
When the first angel sounded his trumpet a third of the trees were burned up and all the green grass was burned up, and when the fifth angel sounded his trumpet the locusts were ordered not to harm the grass, etc.
Did the grass, trees and plants grow again between the sounding of the first and fifth trumpets? Or, was the fifth trumpet the first trumpet to be sounded.
