When they had laid their hands. The laying on of hands followeth prayers, whereby they testify that the grace of the Spirit is not included in the external ceremony, which they crave humbly at the hands of another. And yet when they confess that God is the author, they neglect not the ceremony which was delivered them by God to this use; and because they usurp it not rashly, the effect is also annexed. This is the profit and efficacy of signs, because God worketh in them, and yet he remaineth the only giver of grace and distributeth the same according to his good pleasure; but let us remember that the laying on of hands was the instrument of God, at such time as he gave the visible graces of the Spirit to his, and that since the Church was deprived of such riches, it is only a vain visor without any substance.

1 - "Inane duntaxat esset spectrum," it was only an empty specter.
Then laid they their hands - This was an act of "prayer," expressing an invocation to God that he would impart the blessing to "them." On "how many" they laid their hands is not said. It is evident that it was not on "all," for they did not thus lay hands on Simon. Perhaps it was done on a few of the more prominent and leading persons, who were to be employed particularly in bearing witness to the truth of the gospel. It was customary to lay the hands on any person when a "favor" was to be conferred or a blessing imparted. See notes on Matthew 9:18.
Then laid they their hands on them - Probably only on some select persons, who were thought proper for public use in the Church. They did not lay hands on all; for certainly no hands in this way were laid on Simon.
Then laid they their hands on them,.... The Ethiopic version adds, "who had been baptized"; but not upon all of them, men and women, only on some they were directed unto by the Spirit of God; whom he had designed, and now would qualify for the work of the ministry, that so this new church, might be supplied with proper officers, pastors, and teachers, to feed them with knowledge and with understanding, and who might not only have ministerial gifts to qualify them for preaching the Gospel, but extraordinary ones, which would serve for the confirmation of it; and for this purpose the apostles, "both" of them, as the Arabic version reads, laid their hands on them: for it will not seem probable, that they laid their hands upon the women, on such an account; and it will hardly be received, that they should lay their hands on Simon Magus, otherwise he would have received the Holy Ghost too; so that it seems a plain case, that imposition of hands was not used to them all:
and they received the Holy Ghost; that is, they received the gifts of the Holy Ghost; so that they could prophesy and speak with tongues, and heal diseases, and do other wonderful works: and since now these effects have ceased, the rite and ceremony which was peculiar to the apostles as such, it should seem should cease likewise.
