It is worthy of wonder that, though they found no occasion in Stephen's words for killing him, they still rage and seek such a cause. Those who act unjustly are always malicious in this way. Just as the chief priests were perplexed and said, "What shall we do with these men?" (Acts 4:16), so these men too are torn within. It might seem that he should have been indignant. He had done nothing unjust, yet suffered the lot of the unjust and was slandered. But by this the slanderers are all the more exposed. Thus what I have always said proves true: to do evil is to suffer. He utters no slander, but speaks the truth. So when we are reproached for what we do not know ourselves to have done, we suffer nothing from it. They wanted to kill him, yet they did not do it at once.

Or they deliberately postponed the murder to give the appearance that they did not kill him for rebuking them, just as with Christ, but for impiety. Yet his words were words of piety. Therefore, intending to harm both his life and his glory, they "were cut to the heart." They feared that something new might yet arise because of him.
