Much like Joseph was sold into slavery by his brethren, it was God's doing to save all our lives.
This shows a total lack of understanding of what happened in the Genesis passages.
Orthodox Jews have no scripture for Satan?
You have overlooked them.
The scripture above doesn't say "angels that turn themselves into light"
You have mis-quoted the scripture.
The scripture said; "Satan is transformed into an angel of light"
That means he can appear as a messenger of truth. A minister of righteousness.
He doesn't just appear as "the devil" tempting mankind to turn from God.
He appears as a minister of righteousness claiming to speak for God, but adding to or taking away from the Word of God.
You can quote "Satan" to mean anything you want apparently. Unfortunately, I can't. But yes that's right...in the TORAH the 5 books given from G*d, the word "Satan" שטן does not appear even one time.
The word "satan" is similar to another word in Hebrew commonly used "Ploni" which means "so and so" or "any random person". So in Hebrew texts when the word "Satan" is used it means "Any random accuser that you might encounter..." Before you randomly argue some inane point...try re-reading some lines with the words "An accusing person" in place of "Satan" and see if they make sense.
Here's an example:
"9 Then the accuser answered the LORD, and said: 'Doth Job fear God for nought?"
"But put forth Thy hand now, and touch all that he hath, surely he will blaspheme Thee to Thy face.' "
We're talking about an evil saddistic man who wants to take joy from Job by taking from all his HARD WORK. Thus the accusing man is accusing because he says "He fears G*D? Let's make his life miserable."
What's another similar example of this? Haman...from the book of Esther.
