Acts 13:9

Then Saul . . . also . . . called Paul--and henceforward Paul only; a softening of his former name, in accommodation to Roman ears, and (as the word signifies "little") probably with allusion as elsewhere to his insignificance of stature and appearance (Co2 10:1, Co2 10:10) [WEBSTER and WILKINSON]. filled with the Holy Ghost--the Spirit coming mightily upon him. set his eyes on him and said--Henceforward Barnabas sinks into the background. The whole soul of his great colleague, now drawn out, as never before, shoots, by the lightning gaze of his eye, through the dark and tortuous spirit of the sorcerer. What a picture!

We have not yet met with any things concerning the spreading of the gospel to the Gentiles which bears any proportion to the largeness of that commission, "Go, and disciple all nations." The door was opened in the baptizing of Cornelius and his friends; but since then we had the gospel preached to the Jews only, Act 11:19. It should seem as if the light which began to shine upon the Gentile world had withdrawn itself. But here in this chapter that work, that great good work, is revived in the midst of the years; and though the Jews shall still have the first offer of the gospel made to them, yet, upon their refusal, the Gentiles shall have their share of the offer of it. Here is, I. The solemn ordination of Barnabas and Saul, by divine direction, to the ministry, to the great work of spreading the gospel among the nations about (and it is probable that other apostles or apostolical men dispersed themselves by order from Christ, upon the same errand (Act 13:1-3). II. Their preaching the gospel in Cyprus, and the opposition they met with there from Elymas the sorcerer (Act 13:4-13). III. The heads of a sermon which Paul preached to the Jews at Antioch in Pisidia, in their synagogue, which is given us as a specimen of what they usually preached to the Jews, and the method they took with them (v. 14-41). IV. The preaching of the gospel to the Gentiles at their request, and upon the Jews' refusal of it, wherein the apostles justified themselves against the displeasure which the Jews conceived at it, and God owned them (Act 13:42-49). V. The trouble which the infidel Jews gave to the apostles, which obliged them to remove to another place (Act 13:50-52), so that the design of this chapter is to show how cautiously, how gradually, and with what good reason the apostles carried…

13:9 Luke makes the significant transition from the name Saul (a Hebrew name) to Paul (a Greco-Roman name), perhaps indicating that Paul was now on a predominantly Gentile mission. For the rest of the book of Acts, he is called Paul except when he recounts his conversion (as in 22:7, 13; 26:14).
