Lucifer is Latin. The Hebrew says ‘ben shachar’ - son of the morning, which, curiously, is also there in English along with the Latin Lucifer (with a capital ‘L’) added for purely theological reasons.
I can’t think of any other place where a Latin name is added to what is already an English translation of a phrase in question.
The Nebuchadnezzar reference also makes sense for the subsequent part of the chapter.
Thanks. It seems like Chabad.org is a treasure trove for someone wanting to know more about Scriptures. I am a Christian, but if it seems like the New Testament contradicts the Tanakh, it is obvious that the problem is with me, I am misunderstanding either one (or both). Thanks again.
