I don't think we know enough about the situation to make a final declaration.
I will say that I looked up Believe Music and found several sites that label them a copyright troll. It looks like they are usually over-inclusive in their content ID matches, and thus they match things that absolutely should not be matched.
And I think that what the topic creator is trying to say is that Bethlehem is an artist signed with Prophecy Productions, so why would Believe Music be claiming the songs?
Well, I went to Prophecy Productions BroadCast's channel and saw within Statfire Channelytics that Believe Music is their network (and all videos that Prophecy has posted are monetized by Believe Music). So it would seem that Prophecy is officially working with Believe. This may be recent; I do not know the details. Believe Music may be trying to consolidate who posts what videos where. These are things we cannot know the details to.
