In the OT, Satan is mentioned by name in I Chronicales, Job, and Zechariah, and Psalm 109.6 among other things. There is nothning to identify the King of Sydon with Satan nor the King of Babylon.
The New testament is very clear that Christ considered Satan tre fallen angel also known as the devil, but that's not what the subject was about.
Then kindly tell me who the cherub in the garden of Eden was
Ezekiel 28:12
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.
28:13
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.
28:14 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.
28:15 Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee.
