Mark 5:18-20

18And when he was come into the ship, he that had been possessed with the devil prayed him that he might be with him.

19Howbeit Jesus suffered him not, but saith unto him, Go home to thy friends, and tell them how great things the Lord hath done for thee, and hath had compassion on thee.

20And he departed, and began to publish in Decapolis how great things Jesus had done for him: and all men did marvel.
