Cedar refers to a tree whose wood is used as a very precious material in the Bible.
Its English name is Cedar, and in Korean, it means Samnamu (Japanese cedar).
In the Bible, it was used as pillars for building the Temple. This cedar was transported from the Gentile region of Lebanon and used as pillars for the Temple.
This was the same for both Solomon's Temple and Zerubbabel's Temple.
This symbolizes that the composition of the cosmic church in the Kingdom of God is primarily made up of Gentiles.
The decorations on the pillar capitals are made of lilies, which symbolize the Jews.
