In context
11He is the stone that you the builders threw away, and it has become the cornerstone. 12There is salvation in no one else, for there is no other name under heaven given among people by which we must be saved.” 13Seeing the boldness of Peter and John, and realizing that they were untrained, ordinary men, they were astonished; and they recognized them as men who had been with Jesus. 14And since they could see the healed man standing there with them, they had nothing to say against it. 15So they ordered them out of the Sanhedrin and conferred with one another.
