Acts 26:9

9-11. To still further illustrate his former standing among the Pharisees, he describes his original relation toward the cause of Christ. (9) " I thought with myself that I ought to do many things contrary to the name of Jesus, the Nazarene, (10) which I also did in Jerusalem. Many of the saints I shut up in prison, having received authority from the high priests; and when they were put to death, I gave my vote against them. (11) And in all the synagogues I punished them often, compelling them to blaspheme; and being exceedingly mad against them, I persecuted them even to foreign cities. " With such a record as this, there was no room to suspect him of any such bias as would render him an easy or a willing convert to Christ. On the contrary, it must have appeared to Agrippa, and the whole audience, most astonishing that such a change could take place. Their curiosity to know what produced the change must have been intense, and he proceeds to gratify it.
