Acts 23:2-5

2[At this] the high priest Ananias ordered those who stood beside him to strike Paul on the mouth.

3Then Paul said to him, “God is going to strike you, you whitewashed wall! Do you actually sit to judge me according to the Law, and yet in violation of the Law order me to be struck?”

4But those who stood near Paul said, “Are you insulting the high priest of God?”

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