Someone on Facebook asked me about this interesting post:
Ooh, sounds scary. I don't want to come across any "dangerous names".
Although I know it's sometimes hard to tell, most people aren't complete idiots. If you tell them an obvious lie, they can usually tell, and they'll just ignore or mock you. If you want them to believe it, you have to spend a lot of time conditioning them to believe nonsense (see the current trans-mania) or you have to disguise your nonsense with a veneer of truth. That's what this person is doing. It's total nonsense, but it's couched in just enough truth and true-sounding gobbledygook to seem believable.
This warning(?) sounds plausible if you don't know any Hebrew, nor how languages interact and evolve, nor how to use the tools to verify its claims.
According to the Online Etymology Dictionary, Lucifer is a Latin word that means "light bearer" or "morning star".
According to the Brown-Driver-Briggs Hebrew dictionary, helel means "shining one" or "morning star". It appears only once in the entire Bible in Isaiah 14:12.
When Jerome translated the Bible into Latin in the 4th century, he translated this word literally from the Hebrew to the Latin. That's pretty reasonable, since there is nothing in the context to indicate that it is the name of a person. The Jewish Publication Society and the English Standard Version both translate it as "day star", although the ESV capitalizes it as a proper title. Jerome wasn't trying to hide the original Hebrew, he was just translating it.
The Hebrew word isn't "Hel-El" and did not refer to a "Hel god". The Hebrew is helel (הילל), related to another Hebrew word halal (הלל), which is a verb that means "to shine". It is not a compound word made from hel and el, a generic Hebrew word for a god. It is a deverbal noun derived from a single verb. As far as I can tell, there was no deity named "Hel" in the Ancient Near East, so rendering helel as "Hel god" is doubly nonsensical.
Since almost all early churches in England exclusively used Jerome's Latin Bible, the word "lucifer" was eventually adopted into the Old English language as a pseudonym of Satan. The King James Version translated Hebrew helel as Lucifer, because that was a reasonable translation for the English of that day. Nobody was hiding any "dangerous names".
Lucifer and helel both mean "light bearer". They are synonyms. 2 Corinthians 11:14 says so also: "Satan disguises himself as an angel (messenger/bearer) of light."
The only conspiracy here is by someone trying to make Bible believers look foolish. Beware of peddlers of sensationalism. They are almost always trying to trick you into something.
Now I'm just waiting for someone to claim that drinking Shiner beers is pagan.
