Acts 14:1-3

Now it happened in Iconium that they went together to the synagogue of the Jews, and so spoke that a great multitude both of the Jews and of the Greeks believed. But the unbelieving Jews stirred up the Gentiles and poisoned their minds against the brethren. Therefore they stayed there a long time, speaking boldly in the Lord, who was bearing witness to the word of His grace, granting signs and wonders to be done by their hands.
