Then will you admit that there are no such angel as Lucifer in the Hebrew scriptures?
The original context in the original language of the book of Isaiah make no assumption that the morning star was ever angel. Will you admit that?
Rakhel and other Jews know very well of Christian interpretations of Isaiah, but as far as they are concern, you (not just you personally, but in general all...)Christians are wrong as far the assumptions and interpretations go.
The Hebrew scriptures which you'd call Old Testament, is Jewish, so therefore required Judaic interpretation. I am neither Jewish nor Christian (being agnostic), but from my stand point, I happen to agree with the Jewish interpretation.
The concept of good and evil angels are foreign to the Jewish faith, barring the Jewish Gnosticism, Kabbalah, and other Jewish mysticism.
There were no hierarchical angeleology prior to being banished to Babylon. There were no good and evil angel, war in heaven, or even the possibility of afterlife until the publication of
pseudepigraphal writings, like the
Books of Enoch and
Book of Jubilees, which influenced by Greek and Egyptian religions of the Hellenistic period. All of these dualistic concepts were foreign to Judaism prior to the Exile period.
Satan was never evil until the pre-Christian Hellenistic writing of Enochian literature. To the Jews in the Book of Job, Satan wasn't evil, like the Christian Devil, because Satan had specific role as servant of God, doing God's bidding.
Until you understand the Jewish position in relation to the historicity of Satan, then don't assume that the Jews agree with your view. As far as they concern, Christians, as well as Muslims, have hijacked and corrupted their religion with pagan ideas.
Again, I would suggest that you read
Jews only: War in Heaven thread that I mentioned earlier. It will give you insight as to why Jews don't believe in Christian concepts of angels and demons, of war in heaven, and of dualism. All these elements that Christians believed in, originated from pagan belief.
