Acts 22:30-23:6
But on the next day, desiring to know the real reason why he was being accused by the Jews, he unbound him and commanded the chief priests and all the council to meet, and he brought Paul down and set him before them.
And looking intently at the council, Paul said, “Brothers, I have lived my life before God in all good conscience up to this day.” And the high priest Ananias commanded those who stood by him to strike him on the mouth. Then Paul said to him, “God is going to strike you, you whitewashed wall! Are you sitting to judge me according to the law, and yet contrary to the law you order me to be struck?” Those who stood by said, “Would you revile God’s high priest?” And Paul said, “I did not know, brothers, that he was the high priest, for it is written, You shall not speak evil of a ruler of your people.’”
