Jay-Z calls himself Hova, is he refering to God? ?

There are also plenty of YouTube videos citing references to Jay Z's connection with the Freemasons, which have been connected with the occult (anything supernatural not having to do with God, that is umed to be the work of an evil entity). They're interesting videos to watch, and take from them what you will, but, in my opinion, it's just people with too much time on their hands digging too deep into something. Then again, who knows? Maybe he is.
