“But shewed first unto them of Damascus, and at Jerusalem, and throughout all the coasts of Judaea, and then to the Gentiles, that they should repent and turn to God, and do works meet for repentance.”
King James Version (KJV)
26:20 I declared - From that hour to this, both to Jew and Gentile, that they should repent - This repentance, we may observe, is previous both to inward and outward holiness.
Ac 26:20 First to them of Damascus. He not only was baptized by Ananias in Damascus, but, after some preparation, he began to preach. And then at Jerusalem. Where he disputed against the Grecians (Ac 9:27-29). Throughout the region of Judaea. Just when he preached there we are not informed. Hackett thinks it was when he came up with help at the time of the famine (Ac 11:30). That they should repent. He preached more than a theory; he preached a new life.
