Acts 26:10-12

10And that is what I did in Jerusalem. With authority from the chief priests I put many of the saints in prison, and when they were condemned to death, I cast my vote against them. 11I frequently had them punished in the synagogues, and I tried to make them blaspheme. In my raging fury against them, I even went to foreign cities to persecute them.

12In this pursuit I was on my way to Damascus with the authority and commission of the chief priests.
