Acts 23:2-5
23:2 At that the high priest Ananias ordered those standing near Paul to strike him on the mouth.
23:3 Then Paul said to him, “God is going to strike you, you whitewashed wall! Do you sit there judging me according to the law, and in violation of the law you order me to be struck?”
23:4 Those standing near him said, “Do you dare insult God’s high priest?”
23:5 Paul replied, “I did not realize, brothers, that he was the high priest, for it is written, ‘You must not speak evil about a ruler of your people.’”
