EOM asks: "It says he was full of wisdom and perfect in beauty. He is the annointed cherub 'that is covering'. What exactly does that mean, the annointed cherub that is covering?"
Satan is one of the "covering cherubs" depicted on top of the Ark of the Covenant. Jesus Christ is the other one. Thus Satan was unique at one time in a special position of holiness along with Jesus Christ (Michael, the archangel). The Ark of the Covenant represens Holy Mount Zion out of which Satan was cast at his rebellion.
The two covering cherubs were considered husband and wife and thus the relationship with Jesus Christ at first with Satan was extremely special and extremely close. Of course, it is appropriate that Jesus' wife in heaven would be the most beautiful angel in heaven. But this beauty and "wisdom" corrected Satan.
Genesis 3:15 thus calls Satan "the woman" and the reference to the "woman and her seed" is a reference to Satan and his/her rebel angels. Now it is clear to most that the indictments in Eden pronounced by Jehovah was one to Satan, but actually, one was to Jesus as well.
To Michael the Archangel/Jesus Christ: I will put enmity between you and the woman (Satan) and between your seed and her seed (Satan's rebel angels).
To "the woman" Satan: He (Jesus) will bruise you in the head and you will bruise him in the heel.
Thus the five principals addressed in Eden were the literal serpent, Adam, Eve, Jesus and Satan (the woman) and the "covering cherub" depicted on the Ark of the Covenant.
Therefore, the anointed whom Jesus is said to marry later on taken from the earth take Satan's place in heaven as God's temple on holy mount Zion. So you can understand the resentment of the elect by Satan, especially since Christ's new bride is taken from humanity and are elevated higher than any angels.
Now, in passing, the concept that Satan was a woman is very much a part of esoteric Christian artwork, where even on the ceiling of the Sistine chapel you see Satan depicted as a woman. Google "Lillith" and you will find much artwork showing Satan as a snake-woman.
Further, the constellation VIRGO, which depicts a "virgin holding a branch" is just another version of "the woman and her seed" since a branch represents descendants. So Satan as a woman, an extremely beautiful woman survives in pagandom, such as Venus, or the "woman and her seed" as the Modonna and child, the same as a woman holding a branch. She is often depicted as a "virgin", though, because her children are not her own, but adopted from God's household.
Anyway, Satan was originally one of the "covering cherubs" depicted on the Ark of the Covenant. The alternating figures of a cherub and a palm tree is another indication one of the cherubs was considered a feminine figure, and thus the wife to the other covering cherub.
