Charles Spurgeon Commentary Acts 9:21-22

"And 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. But Saul increased the more in strength, and confounded the Jews that dwelt at Damascus, proving that this is the Christ." — Acts 9:21-22 (ASV)

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.

And this is the great thing to prove to the Jew. Oh! when will it come to pass that poor forsaken Israel will know that this is the very Christ? May God grant her restoration very speedily!
