Acts 23:2-5

2And the high priest Ananias commanded them that stood by him to strike him on the mouth. 3Then said Paul to him, God shall smite thee, thou whitewashed wall: for sittest thou to judge me according to 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 knew not, brethren, that he is the high priest: for it is written, Thou shalt not speak evil of the ruler of thy people.
