“"But Peter and John answered and said unto them, Whether it be right in the sight of God to hearken unto you more than unto God, judge ye. For we cannot but speak the things which we have seen and heard. So when they had further threatened them, they let them go, finding nothing how they might punish them, because of the people." The miracles shut their mouths: they would not so much as let them finish their speech, but cut them short in the middle, most insolently. "And Peter and John answered and said unto them, Whether it be right in the sight of God to hearken unto you more than unto God, judge ye." When the terror was abated (for that command was tantamount to their being dismissed), then also the Apostles speak more mildly: so far were they from mere bravery: "Whether it be right," says he: and "We cannot but speak." "Whether it be right in the sight of God to obey you rather than God." Here by "God" they mean Christ, for He it was that commanded them. And once more they confirm the fact of His Resurrection. "For we cannot but speak the things we have seen and heard:" so that we are witnesses who have a right to be believed. Already these as martyrs have borne testimony: set in the battle against all, they said, "We cannot but speak the things we have seen and heard." If the things we speak be false, reprehend them; if true, why hinderest thou? Such is philosophy! Those, in perplexity, these in gladness: those covered with exceeding shame, these doing all with boldness: those in fear, these in confidence. For who, I would ask, were the frightened? those who said, "That it spread no further among people," or these who said, "we cannot but speak the things we have seen and heard?" And these had a delight, a freedom of speech, a joy surpassing all; those a despondency, a shame, a fear; for they feared the people. But these were not afraid of those; on the contrary, while these spake what they would, those did not what they would. Which were in chains and dangers? was it not these last?”

“But Peter and John answered and said unto them,.... With great boldness and courage, and without any fear of man, but in the true fear of God whether it be right in the sight of God; who is omniscient, and sees, and knows all things, all the actions of men, and the springs of them; who is holy, just, and true, and sits and judges among the gods, that which is right: to hearken unto you more than unto God, judge ye: it is not denied that magistrates are to be hearkened to, and obeyed: but not more than God, or in things that are contrary to his nature, will, law, honour, and glory: whatever is agreeable to the law and will of God, commanded by magistrates, should be attended to, and cheerfully obeyed; but what is not should be disregarded, whatever follows upon it: and this was so just and reasonable, that the apostles appeal to the sanhedrim, or council itself, to determine.”

“Whether it be right in the sight of God - As if they had said: Worldly prudence and a consideration of our secular interests would undoubtedly induce us to obey you; but acting as before God, and following the dictates of eternal truth and justice, we dare not be silent. Can it be right to obey men contrary to the command and will of God? When he commands us to speak, dare we hold our tongue? We have received our authority from God through Christ, and feel fully persuaded of the truth by the Holy Spirit which now dwells in us; and we should be guilty of treason against God, were we on any consideration to suppress his testimony. Your own consciences testify that we should be sinners against our heavenly King, were we to act according to your orders; and the conclusion is, that we cannot but speak what we have seen and heard.”

“But Peter and John stopped their mouths, by asking them, if it was reasonable for them to hearken to men rather than to God. For we, say they, (ver. 20.) cannot but speak the things which we have seen and heard. (Witham)”

“But Peter, etc. You who are judges, do your office, not by putting forth a crooked speech, but by judging justly. Behold, the full grain is found in the ear: which before was bending as it were in the blade.”
