“And when the Jews were gone out of the synagogue, the Gentiles besought that these words might be preached to them the next sabbath.”
King James Version (KJV)
13:42 When the Jews were going out - Probably many of them, not bearing to hear him, went out before he had done. The Sabbath between - So the Jews call to this day the Sabbath between the first day of the month Tisri (on which the civil year begins) and the tenth of the same month, which is the solemn day of expiation.
Ac 13:42 When the Jews were gone out. The Revised Version gives a different sense: "As they (Paul and Barnabas) went out", they were asked to speak again the next Sabbath.
