Acts 26:9-13

I verily thought with myself, that I ought to do many things contrary to the name of Jesus of Nazareth.

Which thing I also did in Jerusalem: and many of the saints did I shut up in prison, having received authority from the chief priests; and when they were put to death, I gave my voice against them.

And I punished them oft in every synagogue, and compelled them to blaspheme; and being exceedingly mad against them, I persecuted them even unto strange cities.

Whereupon as I went to Damascus with authority and commission from the chief priests,

At midday, O king, I saw in the way a light from heaven, above the brightness of the sun, shining round about me and them which journeyed with me.
