'Trees' in the Bible

"Do not damage the earth or the sea or the trees until we have put a seal on the foreheads of the servants of our God."

The first angel blew his trumpet, and there was hail and fire mixed with blood, and it was thrown at the earth so that 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.)
