“Et statuentes eos in medio, interrogabant : In qua virtute, aut in quo nomine fecistis hoc vos ?”
“And when they had set them in the midst, they asked, By what power, or by what name, have ye done this?”
“They had Peter and John brought in and began to question them: “By what power or what name did you do this?””
“When they had stood them in the middle of them, they inquired, “By what power, or in what name, have you done this?””
“And when they had set them in the midst, they inquired, By what power, or in what name, have ye done this?”
By what authority? Is it by your own authority, or that of some other, you have healed this lame man? They wished to know if it was a true miracle, or the effects of some secret magic or enchantment. The knowledge of this kind of affairs belonged to them. It was their duty to repress the attempts of false prophets, seducers, and magicians. But they might easily discover that the apostles were far removed from any thing of this kind. The simple narration of the fact was enough to acquit them. (Calmet)
II. The prisoners are arraigned, v. 7. 1. They are brought to the bar; they set them in the midst, for the sanhedrim sat in a circle, and those who had any thing to do in the court stood or sat in the midst of them (Luke 2 46), so Dr. Lightfoot. Thus the scripture was fulfilled, The assembly of the wicked has enclosed me, Ps 22 16. They compassed me about like bees, Ps 118 12. They were seated on every side. 2. The question they asked them was, "By what power, or by what name, have you done this? By what authority do you these things?" (the same question that they had asked their Master, Matt 21 23): "Who commissioned you to preach such a doctrine as this, and empowered you to work such a miracle as this? You have no warrant nor license from us, and therefore are accountable to us whence you have your warrant." Some think this question was grounded upon a fond conceit that the very naming of some names might do wonders, as ch. 19 13. The Jewish exorcists made use of the name of Jesus. Now they would know what name they made use of in their cure, and consequently what name they set themselves to advance in their preaching. They knew very well that they preached Jesus, and the resurrection of the dead, and the healing of the sick, through Jesus (v. 2), yet they asked them, to tease them, and try if they could get any thing out of them that looked criminal.
Verses 5-14 Peter being filled with the Holy Ghost, would have all to understand, that the miracle had been wrought by the name, or power, of Jesus of Nazareth, the Messiah, whom they had crucified; and this confirmed their testimony to his resurrection from the dead, which proved him to be the Messiah. These rulers must either be saved by that Jesus whom they had crucified, or they must perish for ever. The name of Jesus is given to men of every age and nation, as that whereby alone believers are saved from the wrath to come. But when covetousness, pride, or any corrupt passion, rules within, men shut their eyes, and close their hearts, in enmity against the light; considering all as ignorant and unlearned, who desire to know nothing in comparison with Christ crucified. And the followers of Christ should act so that all who converse with them, may take knowledge that they have been with Jesus. That makes them holy, heavenly, spiritual, and cheerful, and raises them above this world.
