Acts 23:2-5

2And the high priest Ananias commanded those who stood by him to strike him on the mouth.

3Then Paul said to him, “God will strike you, you whitewashed wall! For you sit to judge me according to the law, and do you command me to be struck contrary to the law?”

4And those who stood by said, “Do you revile God’s high priest?”

5Then Paul said, “I did not know, brethren, that he was the high priest; for it is written, ‘You shall not speak evil of a ruler of your people.’ ”
