Astonished At The Doctrine Of The Lord

Acts 13:9-12
9 Then Saul, (who also is called Paul,) filled with the Holy Ghost, set his eyes on him,
10 And said, O full of all subtilty and all mischief, thou child of the devil, thou enemy of all righteousness, wilt thou not cease to pervert the right ways of the Lord?
11 And now, behold, the hand of the Lord is upon thee, and thou shalt be blind, not seeing the sun for a season. And immediately there fell on him a mist and a darkness; and he went about seeking some to lead him by the hand.
12 Then the deputy, when he saw what was done, believed, being astonished at the doctrine of the Lord.
