9 hI myself was convinced that I ought to do many things in opposing the name of iJesus of Nazareth. 10 jAnd I did so in Jerusalem. I not only locked up many of the saints in prison after receiving authority kfrom the chief priests, but lwhen they were put to death I cast my vote against them. 11And mI punished them often in all the synagogues and tried to make them nblaspheme, and oin raging fury against them I ppersecuted them even to foreign cities.
