gold lampstand: The golden menorah in the Tabernacle was first described in Exodus 25:31. A similar lampstand was later placed in the new temple. It served as a symbol of God’s purity and holiness and of the light that comes from his revelation.
The two olive trees represent the roles of priest and king in Israel. They symbolize Jeshua and Zerubbabel. The golden oil represents God's Holy Spirit (see also Zechariah 4:12–14).
