acts 9:6 And he trembling and astonished said, Lord, what wilt thou have me to do? And the Lord said unto him, Arise, and go into the city, and it shall be told thee what thou must do. - Free Bible Online

      6. And he, trembling and astonished, said, Lord, what wilt thou have me to do? And the Lord said--(The most ancient manuscripts and versions of the New Testament lack all these words here [including the last clause of Ac 9:5]; but they occur in Ac 26:14 and Ac 22:10, from which they appear to have been inserted here). The question, "What shall I do, Lord?" or, "Lord, what wilt Thou have me to do?" indicates a state of mind singularly interesting (see on Ac 2:37). Its elements seem to be these: (1) Resistless conviction that "Jesus whom he persecuted," now speaking to him, was "Christ the Lord." (See on Ga 1:15, 16). (2) As a consequence of this, that not only all his religious views, but his whole religious character, had been an entire mistake; that he was up to that moment fundamentally and wholly wrong. (3) That though his whole future was now a blank, he had absolute confidence in Him who had so tenderly arrested him in his blind career, and was ready both to take in all His teaching and to carry out all His directions. (For more, see on Ac 9:9).
      Arise, and go into the city, and it shall be told thee, &c.--See on Ac 8:26-28.
