'Trees' in the Bible

In the night I saw [a vision] and behold, a Man was riding on a red horse, and it stood among the myrtle trees that were in the ravine; and behind Him were horses: red, sorrel (reddish-brown), and white.

And the Man who stood among the myrtle trees answered and said, “These are the ones whom the Lord has sent to go throughout the earth and patrol it.”

And the men on the horses answered the Angel of the Lord who stood among the myrtle trees and said, “We have gone throughout the earth [patrolling it] and behold, all the earth sits at rest [in peace and free from war].”

And there are two olive trees by it, one on the right side of the bowl and the other on its left side [supplying it continuously with oil].”

Then he said to me, “This [continuous supply of oil] is the word of the Lord to Zerubbabel [prince of Judah], saying, ‘Not by might, nor by power, but by My Spirit [of whom the oil is a symbol],’ says the Lord of hosts.

Then I said to him [who was speaking with me], “What are these two olive trees on the right side of the lampstand and on its left?”

Wail, O cypress, for the cedar has fallen,Because the magnificent trees have been destroyed;Wail, O oaks of Bashan,For the inaccessible forest [on the steep mountainside] has come down.
