All sorts of variations. John was writing in Greek, ancient Greek and over time words changed meaning. People try to plug in names or use 666 from other Biblical languages to find out who this person is supposed to be. IMHO
I wonder about the Greek, because in the begging of Revelation Christ said, I am Alpha and Omega. In Hebrew it would have been Alef and Tav which has the meaning of OX and Cross. To me, He said I am the sacrificial Ox at the Cross the beginning and the end. Hebrew brings more meaning to me, but I may be wrong. That is why I started this thread.
