OK. Let's go through Ezekiel 28. My comments are in blue. You'll see that the verses cannot be describing Satan. There is a minor similarity at the end, but, then a distinction immediately follows. Also, the cherub mentioned is from Mt. Sinai, Exodus 25, not Eden Genesis 3.
28:1
And the word of the Lord came to me, saying:
28:2
Son of man, say to the prince of Tyre, Thus says the Lord God: Because your heart is raised, and you have said, I am a God, I sit in the seat of God, in the midst of the seas; yet you are a man, and not God, though you set your heart as the heart of God;
( This chapter is addressing the prince of Tyre. A man who claims to be a god. That's not Satan. )
28:3
Behold, you are wiser than Daniel; there is no secret that they can hide from you?
28:4
With your wisdom and with your understanding you have acquired your riches, and have gathered gold and silver into your treasures?
28:5
By your great wisdom and by your trading you have increased your riches, and your heart is raised because of your riches?
( The prince of Tyre has been greatly successful, and believes he did it via his own individual talent. )
28:6
Therefore thus says the Lord God: Because you have set your heart as the heart of God;
28:7
Behold, therefore I will bring foreigners upon you, the most terrible of the nations; and they shall draw their swords against the beauty of your wisdom, and they shall defile your brightness.
28:8
They shall bring you down to the pit, and you shall die the deaths of those who were slain in the midst of the seas.
( God will bring the prince of Tyre down to the pit and punish him. That's not Satan. )
28:9
Will you yet say before him who slays you, I am God? but you shall be a man, and no God, in the hand of him who slays you.
28:10
You shall die the deaths of the uncircumcised by the hand of foreigners; for I have spoken it, says the Lord God.
( God restates, The prince of Tyre is a man. That is not Satan. )
28:11
And the word of the Lord came to me, saying:
28:12
Son of man, raise a lamentation upon the king of Tyre, and say to him, Thus says the Lord God: You are a seal and a paragon, full of wisdom, and perfect in beauty?
28:13
You have been in Eden the garden of God? every precious stone was your covering, the ruby, the crysolithe, and the diamond, the beryl, the onyx, and the jade, the sapphire, the emerald, and the carbuncle, and gold? the workmanship of your settings and of your sockets was in you; in the day that you were created they were prepared?
( The point here is that the king of Tyre was NOT in eden. The king of Tyre was NOT covered with all of these precious stones. )
28:14
You are the anointed kerub that covers? and I have set you so; you were upon the holy mountain of God; you have walked up and down in the midst of the stones of fire?
( The kerub that covers. That's the cherub produced from a single stock of gold which adorns the ark of testamony. )
( Exo 25:18 - And you shall make two kerubim of gold, of hammered workmanship shall you make them, in the two ends of the cover. )
( God is saying here that the king of Tyre is NOT made of Gold )
28:15
You were perfect in your ways from the day that you were created, till iniquity was found in you?
28:16
By the abundance of your goods they have filled your midst with violence, and you have sinned; therefore I have cast you as profane from the mountain of God; and I destroyed you, O covering kerub, from the midst of the stones of fire.
( God is saying the king of Tyre will be cast down. Again, notice its not the cherubim that guard in eden, they are the ones who are covering. )
28:17
Your heart was raised because of your beauty, you have corrupted your wisdom for the sake of your splendor? I have cast you to the ground, I have laid you before kings, that they may behold you.
( Similar to the serpent in eden, yes, the king of Tyre is being cast to the ground. )
28:18
You have profaned your sanctuaries by the multitude of your iniquities, by the iniquity of your traffic; therefore I have brought forth a fire from your midst, it shall devour you, and I will bring you to ashes upon the earth in the sight of all those who behold you.
( Not like the serpent, the king of Tyre will be devoured. The serpent in eden was cursed to the ground, but it devours. )
28:19
All those who know you among the people shall be appalled at you; you have become a terror, and never shall you be any more.
( Generally people describe Satan as decepttive and charming, so, this is not Satan. )
