Acts 26:12

9 For I, truly, was of the opinion that it was right for me to do a number of things against the name of Jesus of Nazareth.

10 And this I did in Jerusalem: and numbers of the saints I put in prison, having had authority given to me from the chief priests, and when they were put to death, I gave my decision against them.

11 And I gave them punishment frequently, in all the Synagogues, forcing them to say things against God; and burning with passion against them, I went after them even into far-away towns.

12 Then, when I was journeying to Damascus with the authority and orders of the chief priests,

13 In the middle of the day, on the road I saw a light from heaven, brighter than the sun, shining round me and those who were journeying with me.

14 And when we had all gone down on the earth, a voice came to me, saying in the Hebrew language, Saul, Saul, why are you attacking me so cruelly? It is hard for you to go against the impulse which is driving you.

15 And I said, Who are you, Lord? And the Lord said, I am Jesus, whom you are attacking.
