Acts of the Apostles 14:1-3

The same thing happened in Iconium. Paul and Barnabas went to the Jewish synagogue and preached with such power that a great number of both Jews and Greeks became believers. Some of the Jews, however, spurned God’s message and poisoned the minds of the Gentiles against Paul and Barnabas. But the apostles stayed there a long time, preaching boldly about the grace of the Lord. And the Lord proved their message was true by giving them power to do miraculous signs and wonders.
