He’s talking to the city of Tyre in Ezekiel, not Satan. He’s speaking to Tyre as if Tyre is Satan because Tyre’s sin parallels Satan’s. God uses language that would directly apply to Satan and shows how this language directly applies to Tyre. Equating Satan’s arrogance over his beauty to the prince of Tyre’s arrogance over his prosperity.
What you’re reading in Ezekiel is almost 4000 years after creation. Satan was already cast down and the details of his banishment from heaven was already recorded by Isaiah a couple hundred years before Ezekiel’s prophecy.
[Ezekiel 28:12-15] Son of man, take up a lamentation upon the king of Tyrus, and say unto him, Thus saith the Lord GOD; Thou sealest up the sum, full of wisdom, and perfect in beauty. Thou hast been in Eden the garden of God; every precious stone was thy covering, the sardius, topaz, and the diamond, the beryl, the onyx, and the jasper, the sapphire, the emerald, and the carbuncle, and gold: the workmanship of thy tabrets and of thy pipes was prepared in thee in the day that thou wast created. Thou art the anointed cherub that covereth; and I have set thee so: thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire. Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee.
So....it's your position that the King of Tyre was full of wisdom and perfect in beauty; He was in the Garden of Eden and was covered with precious stones; He was an anointed cherub and had been on the Holy Mountain of God; He walked on stones of fire and had been perfect in all his ways until sin was found in him?
I don't really believe that Ezekiel thought that the King of Tyre was an anointed cherub......some may...but I don't.
The above verses show that Satan had an exalted position on Earth prior to Eden.....and was brought down. He did not have this position when Adam was created nor could these facts be true of him on the Earth since he regained dominion through Adam. Ezekiel teaches that Lucifer had a prior kingdom on this Earth.
