Acts 26:13-15

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. And when we were all fallen to the earth, I heard a voice speaking unto me, and saying in the Hebrew tongue, Saul, Saul, why persecutest thou me? it is hard for thee to kick against the pricks. And I said, Who art thou, Lord? And he said, I am Jesus whom thou persecutest.
