Lucifer is an Italian word meaning - LIGHT or Glorified. OR PRAISED ONE
When the Trinitarian Roman Catholic Translators Translated the Bible into English in 1582 " The Douay Rheims " the translators simply refused to translate the Hebrew word { HALLAL } meaning PRAISED .
they left this Hebrew word in Italian - pretending that this word was a Title for Satan.
In fact " Lucifer does not exist in the Hebrew or Greek manuscripts - Lucifer or LIGHT or PRAISED " was never a name - given to Satan in the Bible.
this Hebrew word " הָלַל " HALAL appears in the Old Testament a total of 26 total times.
Isa 4:12 = is about the king of Babylon - not about Satan - and Satan had not fallen from heaven until after Yahashua The Son Of God was conceived upon the earth.
