Acts 9:20-22

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

21 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 here for that intent, that he might bring them bound to the chief priests?

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