Acts 22:11 (KJV)

And it came to pass, that, as I made my journey, and was come nigh unto Damascus about noon, suddenly there shone from heaven a great light round about me.

And I fell unto the ground, and heard a voice saying unto me, Saul, Saul, why persecutest thou me?

And I answered, Who art thou, Lord? And he said unto me, I am Jesus of Nazareth, whom thou persecutest.

And they that were with me saw indeed the light, and were afraid; but they heard not the voice of him that spake to me.

And I said, What shall I do, LORD? And the Lord said unto me, Arise, and go into Damascus; and there it shall be told thee of all things which are appointed for thee to do.

And one Ananias, a devout man according to the law, having a good report of all the Jews which dwelt there,

Came unto me, and stood, and said unto me, Brother Saul, receive thy sight. And the same hour I looked up upon him.

And he said, The God of our fathers hath chosen thee, that thou shouldest know his will, and see that Just One, and shouldest hear the voice of his mouth.

For thou shalt be his witness unto all men of what thou hast seen and heard.

And now why tarriest thou? arise, and be baptized, and wash away thy sins, calling on the name of the Lord.
