If the Jews didn't believe in Satan, then it was because they didn't read their own Scriptures. Starting in Genesis, he is referred to as the "serpent" who deceived Eve. There are many scriptures that speak of "evil spirits". We see in Isaiah 14:12, that he is called "Lucifer" who was at one time "Son of the morning". He was the "anointed cherub", the "Great Dragon". Jesus made references to him many times and the Jewish religious leaders never called him on it - they would have grabbed at anything to trip him up. In Revelation we are given many references reiterating the same titles such as in Rev. 8:10 and Rev. 12:9.
Oh sure, that must be it! They need Christians to teach them their what's in their own scriptures. LOL!

There is no Satan in the Garden because he appears elsewhere in the Old Testament as an angel of God, his prosecutor general, and the word Satan itself is not always applied only to him. It's a title. Perhaps you need to learn Jewish scriptures a little better.
Lucifer is a word invented by Jerome in the 6th century AD. The morning star is a Babylonian deity, like Baal is the Phoenician deity and therefore an idol (or devil), not an angel of God which Satan is clearly identified as in Job.

Revelation is hardly a Jewish scripture. Christian scriptures were written to reinterpret the Old Testament and make it "christianized" the way the Book of Mormon tries to "momonize" both the Old and the New Testaments.
