And when he had called to him his twelve disciples,.... These persons had been for some time called by the grace of God, and were already the disciples of Christ, and such as were more familiar and intimate with him, than others, that went by that name.
They had sat down at his feet, and had received of his words; they had heard his doctrines, and had seen his miracles, and had been by him training up for public work; but as yet had not been called and sent forth to enter on such service: but now all things being ready, they being properly instructed, and the time for the conversion of a large number of souls being up, he called them together privately; and gave them a commission to preach the Gospel, ordained them ministers of the word, and installed them into the office of apostleship.
The number "twelve", is either in allusion to the twelve spies that were sent by Moses into the land of Canaan, or to the twelve stones in Aaron's breast plate; or to the twelve fountains the Israelites found in the wilderness; or to the twelve oxen on which the molten sea stood in Solomon's temple; or to the twelve gates in Ezekiel's temple; or rather, to the twelve patriarchs, and the tribes which sprung from them; that as they were the fathers of the Jewish nation, which was typical of God's chosen people; so these were to be the instruments of spreading the Gospel, not only Judea, but in all the world, and of planting Christian churches there.
And that they might appear to come forth with authority, and that their doctrine might be confirmed,he gave them power against unclean spirits, to cast them out; or "over all devils", as Lu 9:1. It was usual with the Jews to call a demon or devil hamwj xwr, "an unclean spirit"; especially such as frequented burying places: so in one place , an unclean spirit is interpreted by the gloss, Mydv xwr, "the spirit of the demons", or devils; and in another place, twrbqh tyb dv, "the demon of the graves"; where necromancers sought to be, that these spirits might be their familiars, and assist them in their enchantments: accordingly the devils are here called, "unclean spirits"; being in themselves, in their own nature, unclean, and being the cause and means of defiling others, and delighting in impure persons, places, and things.
There were many of these spirits, who, because of the great impiety of the Jews, the prevalence of magic arts among them, and by divine permission, had at this time taken possession of great numbers of persons; whereby Christ had an opportunity of giving proof of his deity, of his being the Messiah, the seed of the woman, that should bruise the serpent's head, by his ejecting them; and of confirming the mission of his disciples, and establishing the doctrine preached by them, by giving them power and authority over them, to cast them out also: and whereas various diseases frequently followed and attended such possessions; he likewise gave them powerto heal all manner of sicknesses, and all manner of diseases, as he himself had done.
The expressions are very full and strong, and include all sorts of maladies incident to human bodies, either of men or women; all distempers natural or preternatural, curable or incurable, by human methods: so that at the same time they were sent to preach the Gospel, for the cure of the souls of men, they were empowered to heal the diseases of their bodies; and which, one should think, could not fail of recommending them to men, and of ingratiating them into their affections.
