Acts 13:6

6, 7. Luke is entirely silent in reference to the effect of the apostolic preaching in Salamis, leaving us to suppose that it was not great. After stating that they preached in the synagogues of the Jews, he follows them in their further progress through the island. (6) "And having passed through the whole island as far as Paphos, they found a certain magician, a false prophet, a Jew whose name was Bar-Jesus, (7) who was with Sergius Paulus the proconsul, a prudent man, who called for Barnabas and Saul, and desired to hear the word of God." Every reader of ancient history has observed that statesmen and generals were in the habit of consulting oracles and auguries, and that they generally kept about them some one supposed to have the power of interpreting the signs of approaching good or evil. In this particular period, the educated Romans had become skeptical in reference to their heathen oracles, but Jewish pretenders still had access to their confidence on the credit of the ancient Jewish prophets. With a knowledge of the true God superior to that of even the greatest philosophers among the Greeks, because derived from the Jewish Scriptures, this Bar-Jesus very naturally gained the confidence of even the prudent Sergius Paulus. When, however, two other Jews appeared in Paphos, claiming to bring additional revelations from the God of Israel, the same prudence which had prompted the proconsul to reject the heathen oracles in favor of the Jewish pretender, now prompted him to send for Barnabas and Saul, that he might hear the word of God from them. Such a mind as his could not fail to hear with profit.
