Acts 9:3-5

And as he journeyed, he came near Damascus: and suddenly there shined round about him a light from heaven:

And he fell to the earth, and heard a voice saying unto him, Saul, Saul, why persecutest thou me?

And he said, Who art thou, Lord? And the Lord said, I am Jesus whom thou persecutest: [it is] hard for thee to kick against the pricks.
