Acts 22:3-5

22:3 “I am a Jew, born in Tarsus in Cilicia, but brought up in this city, educated with strictness under Gamaliel according to the law of our ancestors, and was zealous for God just as all of you are today. 22:4 I persecuted this Way even to the point of death, tying up both men and women and putting them in prison, 22:5 as both the high priest and the whole council of elders can testify about me. From them I also received letters to the brothers in Damascus, and I was on my way to make arrests there and bring the prisoners to Jerusalem to be punished.
