Acts 26:9-11

9Of course, I myself was convinced that it was necessary to do many things hostile to the name of Jesus the Nazarene.

10And that is what I did in Jerusalem: Not only did I lock up many of the saints in prisons by the authority I received from the chief priests, but I also cast my vote against them when they were sentenced to death.

11I punished them often in all the synagogues and tried to force them to blaspheme. Because I was so furiously enraged at them, I went to persecute them even in foreign cities.
