Acts 22:18

and saw him saying unto me In Acts 9:29-30 no mention is made that a vision had appeared to Saul commanding him to depart from Jerusalem. It is only said that "the disciples" sent him away. But these two statements are not inconsistent with each other. Saul might be warned to go, and the disciples at the same time prompted to send him. In the same way two different causes, one natural, the other supernatural, are mentioned Acts 13:2-4, viz. the prompting of the Holy Spirit, and the act of the Church of Antioch. And still more like is the statement of St Paul (Galatians 2:2), that he went up to Jerusalem "by revelation," when it is placed side by side with Acts 15:2 where we are told that the Christians of Antioch determined that Paul and Barnabas should go up to consult the church in Jerusalem.

get thee quickly out of Jerusalem We know from Galatians 1:18 that the duration of the Apostle's stay was but fifteen days.

receive thy testimony concerning me Better (with Rev. Ver.), "receive of thee testimony, &c." The Apostle, as is clear from what follows in the next verse, considered that he would be specially a messenger likely to persuade and convince men of the truths of the Christian faith. God, in the vision, points out that this will not be so.
