Mark 5:15-20

They came to Jesus and saw the demoniac sitting there, clothed and in his right mind, the very man who had had the legion; and they were afraid. Those who had seen what had happened to the demoniac and to the swine reported it. Then they began to beg Jesus to leave their neighborhood. As he was getting into the boat, the man who had been possessed by demons begged him that he might be with him. But Jesus refused, and said to him, “Go home to your friends, and tell them how much the Lord has done for you, and what mercy he has shown you.” And he went away and began to proclaim in the Decapolis how much Jesus had done for him; and everyone was amazed.
