Luke 8:38

But the man from whom the demons were gone out prayed him that he might be with him: but he sent him away, saying, Return to thy house, and declare how great things God hath done for thee. And he went his way, publishing throughout the whole city how great things Jesus had done for him.

The Lord granted the request of the demons, but did not grant this man's prayer. This was due to the fact of our Lord's making him a witness of the truth in a district that might otherwise have been without a witness. Jesus' command that the man should publish abroad the fact of his healing, whereas upon other occasions Jesus forbade such publication, was due to the different circumstances. There was nothing in this wonder that could be perverted to political purposes; and the publication of this miracle was focused upon the works of Jesus, rather than bearing upon his identity. Nevertheless, there was a most vivid glimpse of the Lord's deity:

"Declare how great things God hath done for thee." "How great things Jesus hath done for him."

This witness of Christ's power spread throughout the whole region; and later, Jesus healed a deaf-mute in one of the cities where this man had proclaimed Jesus (Mark 7:32). See my Commentary on Mark for discussion of that miracle.

ONE MIRACLE EMBEDDED IN ANOTHER

All the synoptics record the raising of the daughter of Jairus, along with the parenthetical wonder of his healing the woman with the issue of blood; and their agreement is not any evidence that all of these sacred records were derived from some single prior source, but proves that this is the way it all actually happened.
