Acts 9:20-22

20Immediately he preached the Christ in the synagogues, that He is the Son of God.

21Then all who heard were amazed, and said, “Is this not he who destroyed those who called on this name in Jerusalem, and has come here for that purpose, so that he might bring them bound to the chief priests?”

22But Saul increased all the more in strength, and confounded the Jews who dwelt in Damascus, proving that this Jesus is the Christ.
