After that I saw a great crowd which no one could count from every nation, tribe, people, and language, standing before the throne and before the Lamb, wearing white robes, with palm branches in their hands,

"Do not harm the earth or the sea or the trees until we mark the slaves of our God on their foreheads."

The first blew his trumpet, and there was a storm of hail and fire mixed with blood, and it fell upon the earth, and one third of the earth was burned up, and one third of the trees were burned up, and all the green grass was burned up.

They are the two olive trees and the two lampstands that stand before the Lord of the earth.
