'Trees' in the Bible

"Don't harm the land, the sea, or the trees until we have marked the servants of our God with a seal on their foreheads."

When the first angel blew his trumpet, hail and fire were mixed with blood and thrown on the earth. One-third of the earth was burned up, one-third of the trees was burned up, and all the green grass was burned up.

These witnesses are the two olive trees and the two lamp stands standing in the presence of the Lord of the earth.
