Sure.
Walid Shoeblat says he found Arabic symbols related to the Islamic Allah in Revelations 3:18 of the earliest texts of the bible.
He specifically references the Codex Sinaiticus.
So I look up Rev 3:18 in the Codex Sinaiticus and what he is talking about isn’t there at all. It’s just the greek words for 666.
He also mentions Codex Vaticanus, but the original version doesn’t include a translation of Revelations at all.
So far it doesn’t look like his claims are credible to me.
Thx. This will take some research on my part. Will copy you with what I learn.
