Was the descendant of Cain (called the devil) who tried to tempt Jesus, one of the priest?

and had access to the temple. Cain was the first murderer and liar and therefore Jesus said he was "the devil" and all his descendants are his angels because they bring the same message as their forefather of murdering and lying. The descendant of Cain (the devil) prove who they are by their actions and they are also called the Devil, because they are all one line before God. There are no fallen angels
