(7) He called unto him the twelve.--See Notes on Matthew 10:1-15. The omission by St. Mark of the greater part of the discourse connected with the mission of the Twelve in Matthew 10 is every way characteristic of the writer, whose main work it was to trace the ministry of action rather than of speech.

Verse 7. - At Mark 3:7 we had the account of our Lord's selection of the twelve. Here we find the notice of their being first sent forth. Their names have already been recorded. He gave them authority - mark the imperfect (ἐδίδου) - over unclean spirits. St. Matthew (Matthew 10:1) adds, "and to heal all manner of sickness and all manner of disease." But St. Mark here fixes the attention upon the great central object of Christ's mission - to contend against evil in every form, and especially to grapple with Satan in his stronghold in the hearts of men.

6:7-13 Though the apostles were conscious to themselves of great weakness, and expected no wordly advantage, yet, in obedience to their Master, and in dependence upon his strength, they went out. They did not amuse people with curious matters, but told them they must repent of their sins, and turn to God. The servants of Christ may hope to turn many from darkness unto God, and to heal souls by the power of the Holy Ghost.And he called unto him the twelve,.... "His twelve disciples", as some copies read; whom he had before called by his grace, and had appointed and ordained them his apostles, but had not yet publicly sent forth; in order to which, he now called them to him, and gave them their commission, qualifications, and instructions:

and began to send them forth by two and two: he first sent forth one couple, and then another; the reason of his sending them by pairs, was partly for the sake of company, and that they might be useful and assisting to one another; and partly to show their agreement in doctrine; and that they might be proper and sufficient witnesses of it, whereby it might be established; and the rather, being thus sent by pairs into different parts, their message would be the sooner dispatched, than if they had all went together:

and gave them power over unclean spirits; that is, to cast them out; as it is expressed in Mat_. 10:1; see Gill on Matthew 10:1; and which is here added in the Syriac and Persic versions. Many things are omitted by this evangelist, which are mentioned by Matthew: he does not give us the names of the twelve apostles; the reason of that indeed may be, because they are related by him in Mark 3:16, and he did not choose to repeat them here: nor does he take any notice of the places where the apostles were to go, and where not; nor of the persons to whom, or not; as not into the way of the Gentiles, nor into any of the cities of the Samaritans, but to the lost sheep of the house of Israel: nor does he say any thing of the subject matter of their ministry or what they had in charge to publish; as that the kingdom of heaven is at hand, or the Gospel dispensation: nor does he observe the several things they were to do in confirmation of their doctrine and mission; as healing the sick, cleansing lepers, raising the dead, and casting out devils: he only relates the directions given them with respect to their journey, in the following verses; the reason of all which seems to be, because he refers not to the same time as Matthew does, to their appointment and ordination; but to the time they were sent out, and proceeded on their journey.
