Acts 14:1-3

In Iconium they entered the synagogue of the Jews together, and spoke in such a manner that a large number of people believed, both of Jews and of Greeks. But the Jews who disbelieved stirred up the minds of the Gentiles and embittered them against the brethren. Therefore they spent a long time there speaking boldly with reliance upon the Lord, who was testifying to the word of His grace, granting that signs and wonders be done by their hands.
