Mark 9:14

We have here the story of Christ casting the devil out of a child, somewhat more fully related than it was in Mat 17:14, etc. Observe here, I. Christ's return to his disciples, and the perplexity he found them in. He laid aside his robes of glory, and came to look after his family, and to enquire what was become of them. Christ's glory above does not make him forget the concerns of his church below, which he visits in great humility, Mat 17:14. And he came very seasonably, when the disciples were embarrassed and run a-ground; the scribes, who were sworn enemies both to him and them, had gained an advantage against them. A child possessed with a devil was brought to them, and they could not cast out the devil, whereupon the scribes insulted over them, and reflected upon their Master, and triumphed as if the day were their own. He found the scribes questioning with them, in the hearing of the multitude, some of whom perhaps began to be shocked by it. Thus Moses, when he came down from the mount, found the camp of Israel in great disorder; so soon were Christ and Moses missed. Christ's return was very welcome, no doubt, to the disciples, and unwelcome to the scribes.
