'Trees' in the Bible

I looked out in the night and saw a man riding on a red horse. He was standing among the myrtle trees in the valley. Behind him were red, sorrel, and white horses.

Then the man standing among the myrtle trees explained, “They are the ones the Lord has sent to patrol the earth.”

They reported to the Angel of the Lord standing among the myrtle trees, “We have patrolled the earth, and right now the whole earth is calm and quiet.”

There are also two olive trees beside it, one on the right of the bowl and the other on its left.”

I asked him, “What are the two olive trees on the right and left of the lampstand?”

Wail, cypress, for the cedar has fallen;the glorious trees are destroyed!Wail, oaks of Bashan,for the stately forest has fallen!
