and He healed many of those who were sick with various diseases and drove out many evil spirits. But He did not permit the evil spirits to tell people [who He was], because they knew who He was [i.e., the Christ].
So, Jesus went into the [Jewish] synagogues throughout all Galilee, preaching [the good news about the coming kingdom, verses 14- 15] and driving out evil spirits.
When Jesus saw a crowd running together [toward Him], He spoke sternly to the evil spirit [in the boy], saying to it, “You deaf-mute spirit, I order you to come out of this boy and to never return to him again.”
