Acts 14:1-3

When Paul and Barnabas arrived at Iconium, the same thing happened there. They went, as they always did, to the synagogue and preached to the people with such power that a large crowd of both Jews and non-Jews believed. Some of the Jews refused to believe, and they began to poison the minds of the non-Jews to discredit the believers. Yet Paul and Barnabas stayed there for a long time, preaching boldly and fearlessly about the Lord. Many trusted in the Lord, for he backed up his message of grace with miracles, signs, and wonders performed by the apostles.
