Who are the 24 Elders?

Autous is found 356 times as a third person personal pronoun. I, our, we, us and ours are first person pronouns.  Not to mention, A, (B) Codex Vaticanus, (Aleph) Siniaticus, Vulgate, Syriac and Coptic read it as "they" and "them".  Because the argument goes on, I would not claim this scripture is "translated correctly" which claims all other manuscripts with Rev 5:9-10 are invalid.  There are translators who argue for each.  Gary and others obviously chose the MT. That doesn't invalidate the other. Many people use that text found commonly in our KJV.  And, the KJV has been a very good text overall though I would say there are a few pieces of scripture that may need to be looked at, this being one of them.  It is impossible to explain from the given text why angels would need to be redeemed or reign as kings on earth.  This is not meant to argue or start a thread, but to set the facts straight for others readers that your claim is bias.  

I am sure the hard work that Gary and others put in, blood and sweat, will provide another option for many believers to choose from in gaining a better understanding of God's word and spiritual growth for decades to come.
