Acts 26:10-11

10And that is what I did in Jerusalem. Not only did I lock up many of the kedoshim in prisons by the authority I received from the ruling kohanim, but I cast my vote against them when they were being condemned to death.

11I tried to cause them to blaspheme by punishing them often in the synagogues. In furious rage against them, I persecuted them even in foreign cities.
