Acts 14:1-3

1At Iconium, Paul and Barnabas went as usual into the Jewish synagogue, where they spoke so well that a great number of Jews and Greeks believed. 2But the unbelieving Jews stirred up the Gentiles and poisoned their minds against the brothers. 3So Paul and Barnabas spent considerable time there, speaking boldly for the Lord, who affirmed the message of His grace by enabling them to perform signs and wonders.
