Later, in Acts 4, Peter and John went before Annas and Caiaphas after having healed a crippled man. Caiaphas and Annas questioned the apostles' authority to perform such a miracle. When Peter, full of the Holy Spirit, answered that Jesus of Nazareth was the source of their power, Caiaphas and the other priests realized that the two men had no formal education yet spoke eloquently about the man they called their saviour. Caiaphas sent the apostles away, and agreed with the other priests that the word of the miracle had already been spread too much to attempt to refute, and instead the priests would need to warn the apostles not to spread the name of Jesus. However, when they gave Peter and John this command, the two refused, saying "Judge for yourselves whether it is right in God's sight to obey you rather than God. For we cannot help speaking about what we have seen and heard."
