Arioch is the royal official who King Nebuchadnezzar charges with putting all the wisemen to death. When Daniel asks him to give him some extra time to see if God can help him learn the interpretation of Nebuchadnezzar's dream, Arioch says yes. So, yeah… even though he was about to kill a ton of people, we guess he's an alright guy. That's literally everything you could possibly say about Arioch. That—and his name means "fierce lion" in Hebrew.
