And while Peter and John were talking to the people, the priests and the captain [who was in charge of the temple area and] of the temple guard and the Sadducees came up to them, being extremely disturbed and thoroughly annoyed because they were teaching the people and proclaiming in [the case of] Jesus the resurrection of the dead. So they arrested them and put them in jail until the next day, because it was evening. But many of those who heard the message [of salvation] believed [in Jesus and accepted Him as the Christ]. And the number of the men came to be about 5,000.
On the next day, their magistrates and elders and scribes (Sanhedrin, Jewish High Court) were gathered together in Jerusalem; and Annas the high priest was there, and Caiaphas and John and Alexander, and all others who were of high-priestly descent. When they had put the men in front of them, they repeatedly asked, “By what sort of power, or in what name [that is, by what kind of authority], did you do this [healing]?” Then Peter, filled with [the power of] the Holy Spirit, said to them, “Rulers and elders of the people [members of the Sanhedrin, the Jewish High Court], if we are being put on trial today [to interrogate us] for a good deed done to [benefit] a disabled man, as to how this man has been restored to health, let it be known and clearly understood by all of you, and by all the people of Israel, that in the name of Jesus Christ the Nazarene, whom you [demanded be] crucified [by the Romans and], whom God raised from the dead—in this name [that is, by the authority and power of Jesus] this man stands here before you in good health. This Jesus is the STONE WHICH WAS DESPISED and REJECTED by you, THE BUILDERS, but WHICH BECAME THE CHIEF CORNERSTONE. [Ps 118:22] And there is salvation in no one else; for there is no other name under heaven that has been given among people by which we must be saved [for God has provided the world no alternative for salvation].”
Now when the men of the Sanhedrin (Jewish High Court) saw the confidence and boldness of Peter and John, and grasped the fact that they were uneducated and untrained [ordinary] men, they were astounded, and began to recognize that they had been with Jesus.
