Acts 4:13 (NLT)
13 The members of the council were amazed when they saw the boldness of Peter and John, for they could see that they were ordinary men with no special training in the Scriptures. They also recognized them as men who had been with Jesus.
The religous “big wigs” of the day were completely bumfuzzled by the knowledge and authority these unschooled “hillbillies” possessed. They had been in the presence of Jesus himself. Both crowds.
