Mar 5:18-20 ISV
18 As Jesus was getting into the boat, the man who had been demon-possessed kept begging him to let him go with him.
19 But Jesus wouldn’t let him. Instead, he told him, “Go home to your family, and tell them how much the Lord has done for you and how merciful he has been to you.”
20 So the man left and began proclaiming in the Decapolis how much Jesus had done for him. And everyone was utterly amazed.
