Acts 9:20-22

20And straightway in the synagogues he proclaimed Jesus, that he is the Son of God. 21And all that heard him were amazed, and said, Is not this he that in Jerusalem made havoc of them that called on this name? and he had come hither for this intent, that he might bring them bound before the chief priests. 22But Saul increased the more in strength, and confounded the Jews that dwelt at Damascus, proving that this is the Christ.
