'Trees' in the Bible

“Don’t harm the earth or the sea or the trees until we seal the slaves of our God on their foreheads.”

The first angel blew his trumpet, and hail and fire, mixed with blood, were hurled to the earth. So a third of the earth was burned up, a third of the trees were burned up, and all the green grass was burned up.

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