Mark 5:19-20

19But Jesus did not let him do this. Jesus said to him, ‘Go to your home and to your friends. Tell them what the Lord has done for you. Tell them how he has been kind to you.’

20So the man went away. He began to speak to many people in the region called ‘The ten cities’. He told them about the great things that Jesus had done for him. All the people were very surprised.
