Mark 9:38

John said to him , Teacher , we saw someone casting out demons in your name , and we tried to stop him , because he was not following us .

“Teacher,” said John, “we saw someone driving out demons in your name and we told him to stop, because he was not one of us.”

And John answered him, saying, Master, we saw one casting out devils in thy name, and he followeth not us : and we forbad him, because he followeth not us.
