Luke 8:36-39

They also who had seen it told them by what means he who had been demon-possessed was healed. Then the whole multitude of the surrounding region of the Gadarenes asked Him to depart from them, for they were seized with great fear. And He got into the boat and returned. Now the man from whom the demons had departed begged Him that he might be with Him. But Jesus sent him away, saying, “Return to your own house, and tell what great things God has done for you.” And he went his way and proclaimed throughout the whole city what great things Jesus had done for him.
