And when they had ordained them elders in every church, and had prayed with fasting, they commended them to the Lord, on whom they believed. Acts 14:23
As they ministered to the Lord, and fasted, the Holy Ghost said, Separate me Barnabas and Saul for the work whereunto I have called them. And when they had fasted and prayed, and laid their hands on them, they sent them away. Acts 13:2-3
