Acts 26:9-11

9“I used to believe that I ought to do everything I could to oppose the very name of Jesus the Nazarene.

10Indeed, I did just that in Jerusalem. Authorized by the leading priests, I caused many believers there to be sent to prison. And I cast my vote against them when they were condemned to death.

11Many times I had them punished in the synagogues to get them to curse Jesus. I was so violently opposed to them that I even chased them down in foreign cities.
