Acts 9:18-22

And immediately there fell from his eyes as it had been scales: and he received sight forthwith, and arose, and was baptized.

And when he had received meat, he was strengthened. Then was Saul certain days with the disciples which were at Damascus.

And straightway he preached Christ in the synagogues, that he is the Son of God.

But all that heard him were amazed, and said; Is not this he that destroyed them which called on this name in Jerusalem, and came hither for that intent, that he might bring them bound unto the chief priests?

But Saul increased the more in strength, and confounded the Jews which dwelt at Damascus, proving that this is very Christ.
