And they departed, and preached. Matthew silently passes over what the Apostles did. Mark and Luke relate that they proceeded to execute the commission which they had received; and from their statements it appears more clearly, that the office which Christ at that time bestowed upon them, as I have formerly mentioned, was temporary, and indeed lasted but a few days. They tell us that the Apostles went through the cities and villages: and they unquestionably returned in a short time to their Master, as we shall find to be stated in another passage. The only matter that requires exposition here is the fact related by Mark, that they anointed with oil many diseased persons Christ having conferred on them the power of healing, it is asked, why did they apply oil? Some learned persons suppose that it was a sort of medicine; and I acknowledge that in these countries the use of oil was very common. But nothing is more unreasonable than to imagine, that the Apostles employed ordinary and natural remedies, which would have the effect of obscuring the miracles of Christ. They were not instructed by our Lord in the art and science of healing, but, on the contrary, were enjoined to perform miracles which would arouse all Judea. I think, therefore, that this anointing was a visible token of spiritual grace, by which the healing that was administered by them was declared to proceed from the secret power of God; for under the Law oil was employed to represent the grace of the Spirit. The absurdity of an attempt to imitate the Apostles, by making the anointing of the sick a perpetual ordinance of the Church, appears from the fact, that Christ bestowed on the Apostles the gift of healing, not as an inheritance which they should hand down to posterity, but as a temporary seal of the doctrine of the Gospel. In our own day, the ignorance of the Papists is exceedingly ridiculous in maintaining that their nasty unction, [1] by which they hurry to the grave persons who are fast dying, is a Sacrament.

Preached that men should repent - See the nature of repentance explained in notes at Matthew 3:2. They were now called upon to repent and reform their lives because sin was evil, because the Messiah had come to preach forgiveness to the penitent, and because at "his" presence it was fit that the nation should turn from its sins and prepare to receive him.

And they went out,.... From that part of the country where they then were, some one way, and some another, two by two, with these instructions, and according to these directions; in order to preach the word, and work miracles, in the several parts where they were sent:
and preached that men should repent; both of the evil practices which they were guilty of, and of the bad principles they had imbibed, and change both their sentiments and their conduct: this, they exhorted them to, as John the Baptist, and Christ, had done before, who set out in their ministry the same way; and these, as they did also, preached the Gospel, and the things appertaining to the kingdom of God, and Gospel dispensation, and called upon men to believe them. For faith and repentance went together in Christ's ministry, Mark 1:15, and so they did in the ministry of John, the Baptist, Acts 19:4, and in the ministry of the apostles, Acts 20:21. When they preached that men should repent, it does not from hence follow, that they have a power to repent of themselves: for such is the condition of men by nature, that they neither see their need of repentance, and their hearts are so hard and obdurate, that they cannot work themselves up to it, or work it in them, and exercise it; this requires the powerful and efficacious grace of God to produce it, and it is a gift of his grace; and if he gives the means, and not the grace of repentance itself, it will never appear: but the apostles preaching that men should repent, shows that they were in such a state as to need it; and how necessary it was for them to have it, seeing without it they must all perish: and such a ministration is proper, to awaken the minds of men to a sense of the need of it, and to direct them to Christ the Saviour, who is exalted to give it, as well as the remission of sins.
