Acts 14:21-23

And when they had preached the gospel to that city, and had made many disciples, they returned to Lystra, and to Iconium, and to Antioch, confirming the souls of the disciples, exhorting them to continue in the faith, and that through many tribulations we must enter into the kingdom of God. And when they had appointed for them elders in every church, and had prayed with fasting, they commended them to the Lord, on whom they had believed.
