 As I look at the unfolding of events of verses 12 to 16, I find five subjects that intrigue all of us. They do me when I read through them, and I think they need to be addressed at least briefly so we're all informed. First, there's a mention of an angel, so we need to explain the avenging angel in verse 12, the sixth angel. There's a mention of a river, and its name for us is the Euphrates in verse 12.
