Acts 10:30; Acts 13:2-3

30 And Cornelius said , Four days ago I was fasting until this hour; and at the ninth hour I prayed in my house, and, behold , a man stood before me in bright clothing,
2 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. 3 And when they had fasted and prayed , and laid their hands on them, they sent them away .
