Y’shua told one man who had been delivered from a legion of demons to go back home and to tell all that the Lord had done for him. That man went around telling everyone what Y’shua had done for him.

Luke 8:37. Then all the multitude of the region of the Gerasene asked Him to leave from them, because they were being distressed with great fear: then He returned, having embarked in a boat. 38. And the man from whom the demons had come out was begging Him to be with Him: but He released him saying, 39. “You must return to your house and you must continually tell what God did for you.” Then he left, proclaiming throughout the whole city what Y’shua did for him.
