God created the heavens and the earth (Genesis 1) sometime after the creation of the celestial beings (Job 38: 4-7). Lucifer was given authority over some aspect of the creation as the passage states: you were in Eden the garden of God. This Garden of Eden is not the same as the garden in Genesis. This is a jewel garden. The Genesis Eden is a vegetable garden. This passage describes the original creation being covered in jewels with no oceans or seas. The jewels exuded a light and are so-called as “the stones of fire” in verse fourteen. Satan, walking up and down these had dominion over it for some unknown amount of time. This was before any other earthly being was created. The stones also served as a canopy over Satan. Because the jewels and gold mentioned are almost exactly the same as the breastplate to the High Priest in the Tabernacle the text strongly suggests Satan had a priestly role in the first Garden of Eden.
The term “the workmanship of your tabrets and of your pipes was in you” is a reference to musical instruments, which would add credence to the thought that he was a High Priest in heaven leading worship of God. It can also refer to the sockets, which hold the jewels mentioned. The Hebrew context accommodates both meanings. Finally, the verse says: in the day that you were created they were prepared. This means that from the moment he was created he was assigned certain responsibilities:
• He was the epitome of wisdom and beauty.
• He had musical instruments to use in worship.
• He was probably High Priest in the heavenly Tabernacle.
This is the domain from which he had his fall.
He became prideful and sinned.
