Numbers - Chapter 8
Chapter 8 begins with God giving instructions on setting up the seven lamps in the lampstand. The golden lampstand does not produce light - it is used to hold the lamps, which light up the tabernacle.
Similarly in Revelation chapter 1 we read that the lampstands which John sees represent the church. And the church has the role of showing Jesus - the Light of the World. The lampstand and the lamps work in harmony to bring light into the darkness.
