'Trees' in the Bible

saying, "Do not damage the earth or the sea or the trees until we have sealed the slaves of our God on their foreheads."

And the first blew the trumpet, and there was hail and fire mixed with blood, and it was thrown to the earth, and a third of the earth was burned up, and 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.
