That is talking about the Seven Churches that were in existence in the time of John upon which a judgment was to come upon them soon ...as demonstrated by Revelation 2 and Revelation 3.
Paul use the term OLIVE TREE in Romans 11:24 .
Nothing to do with the TWO OLIVE TREES of Revelation 11:3-4 WHICH ARE IDENTIFY as being TWO WITNESSES.
Revelation 11:3-4
3 And I will give unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.
4 These are the two olive trees and the two candlesticks, standing before the Lord of the earth.

witness to us: for after that he had said before,

witness that he was righteous, God testifying of his gifts: and by it he being dead yet speaketh.

witness of the sufferings of Christ, and also a partaker of the glory that shall be revealed:

his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
