Anyway the rest of what I said was true. Modern Arabic was not a language when the books of the Bible were written. Knowing this doesn't make me an expert on the subject, but I don't think you have to be credentialed to leave a comment here.
John 3:13 says: "no man has ascended into heaven but the one who descended from heaven, the Son of man."
Could it be that Elijah and Enoch went somewhere else?
Those were the names given to them at birth- See Daniel 1:6. Afterall, does anyone know who Belteshazzar is? (It's Daniel, the name he was given at the same time his friends were given the new names of Shadrach, Meshach and Abed-nego). Just because an evil king renames you to try to get you to worship gods you don't believe in, and that you stand against, why should those names be what everyone calls you for all of history? For reference, here are their given names and what they were renamed, with the meanings of each:
Daniel/Belteshazzar-"God is my judge"/"The favorite of Bel [an idol god]"
Hananiah/Shadrach- "Favored of Jah [Jehovah]"/"enlightened by the sun god"
Mishael/Meshach-"Who is what God is?"/"Who can be like the goddess Shach?"
Azariah/Abed-nego-"Jah has helped"/"the faithful servant of the fire god Nego"
“Neither the word Trinity nor the explicit doctrine appears in the New Testament . . . The doctrine developed gradually over several centuries and through many controversies.”
You are echoing the Arian (nothing to do with Nazis, but with a guy named Arias) doctrine of Christology, which, as one of its first official acts, the Church declared a heresy.
They come from the first word of each of the books in Hebrew, although substitute an e for each schwa:
Bəreshit (בְּרֵאשִׁית, literally "In the beginning")—Genesis, from Γένεσις (Génesis, "Creation")
Shəmot (שְׁמוֹת, literally "Names")—Exodus, from Ἔξοδος (Éxodos, "Exit")
Vayikra (וַיִּקְרָא, literally "And He called")—Leviticus, from Λευιτικόν (Leutikón, "Relating to the Levites")
Bəmidbar (בְּמִדְבַּר, literally "In the desert [of]")—Numbers, from Ἀριθμοί (Arithmoí, "Numbers")
"So Moses the servant of the Lord died there in the land of Moab, according to the word of the Lord. And He buried him in the valley in the land of Moab, opposite Beth-peor; but no man knows his burial place to this day." ~ Deuteronomy 34:5-6.
Best guess is that you're thinking of the transfiguration, where Moses and Elijah were with Jesus shortly before he ascended into Heaven. A dead person returning to Heaven doesn't count.
