Acts 26:9-11

I verily thought with myself that I ought to do many things contrary to the name of Jesus of Nazareth. And this I also did in Jerusalem: and I both shut up many of the saints in prisons, having received authority from the chief priests, and when they were put to death I gave my vote against them. And punishing them oftentimes in all the synagogues, I strove to make them blaspheme; and being exceedingly mad against them, I persecuted them even unto foreign cities.
