We must note that all the information I gave earlier is from Paul himself. There is no independent source of information about Paul.
Paul simply takes on the color of the tree that he is on! Acts 8.3: As for Saul, he
rebelled against the disciples of Jesus (a.s), entering into every house and
dragging off men and women committing them to prison
Acts 21.38: He was arrested by the Roman who asked him: Are you not that
Egyptian, who before these days made
rebellion and led out into the wilderness 4,000 men that were
murderers?
The Disciples knew Saul as a persecutor,
a murderer, the Romans knew him as an Egyptian Rebel, and the
Christians know him as a saint? So nobody really knows who this guy is. And neither do I.
But Acts 9.18: And immediately there fell from his eyes as it had been scales.
I know only of fish and serpents as having scales. This reminds me of Genesis 3.1: Now the serpent was more subtle (cunning) than any beast of the field which the Lord God had made. And he said to the woman…. And you know the rest of the story how he led Adam and Eve to break God’s Law and so get thrown out of heaven. This is history repeating itself. It is not easy to understand Paul unless you are very, very, very careful.
