Acts 23:2-5

2And the high priest Ananias commanded them that stood by him to smite him on the mouth.

3Then said Paul unto him, God shall smite thee, thou whited wall: for sittest thou to judge me after the law, and commandest me to be smitten contrary to the law?

4And they that stood by said, Revilest thou God’s high priest?

5Then said Paul, I wist not, brethren, that he was the high priest: for it is written, Thou shalt not speak evil of the ruler of thy people.
