(39) Throughout the whole city.--The city was, of course, according to the reading adopted, Gerasa, or Gadara.

8:22-40 Those that put to sea in a calm, even at Christ's word, must yet prepare for a storm, and for great peril in that storm. There is no relief for souls under a sense of guilt, and fear of wrath, but to go to Christ, and call him Master, and say, I am undone, if thou dost not help me. When our dangers are over, it becomes us to take to ourselves the shame of our own fears, and to give Christ the glory of our deliverance. We may learn much out of this history concerning the world of infernal, malignant spirits, which though not working now exactly in the same way as then, yet all must at all times carefully guard against. And these malignant spirits are very numerous. They have enmity to man and all his comforts. Those under Christ's government are sweetly led with the bands of love; those under the devil's government are furiously driven. Oh what a comfort it is to the believer, that all the powers of darkness are under the control of the Lord Jesus! It is a miracle of mercy, if those whom Satan possesses, are not brought to destruction and eternal ruin. Christ will not stay with those who slight him; perhaps he may no more return to them, while others are waiting for him, and glad to receive him.Return to thine own house,.... Which very likely was in the city of Gadara, whither he went, and throughout the whole of which he published the account of the dispossession of the devils from him: Mark adds, "to thy friends"; relations, acquaintance, and countrymen:

and show how great things God hath done unto thee; for none but God could effect such things, tacitly suggesting to him hereby, that he himself was God. Mark adds, "and hath had compassion on thee": signifying, that what he had done for him, did not arise from merit in the man, but from mercy in himself; See Gill on Mark 5:19.

And he went his way; he obeyed the orders of Christ, as love and gratitude obliged him:

and published throughout the whole city; of Gadara, and not only there, but in the rest of the ten cities, called Decapolis, Mark 5:20 one of which was this of Gadara, as Pliny relates (o):

how great things Jesus had done unto him; having cast out a legion of devils from him, clothed him, and brought him to his right mind; and had not only delivered his body from a diabolical possession, but had given him spiritual and saving instructions for his soul, on which he had wrought a real work of grace.
