Who are the two olive trees and lampstands in the Bible?

In Revelation 11:4, we read about two olive trees and two lampstands that stand before Jesus. The two olive trees symbolize the Holy Spirit's endless supply of anointing, meant to keep the witnesses empowered and lit for the world to hear the Lord's message. The lampstands symbolize Churches. They are the spiritual light shining out to a spiritually dark world.
