Some priests, the officer in charge of the temple guards, and some Sadducees approached Peter and John while they were speaking to the people.
These religious authorities were greatly annoyed. Peter and John were teaching the people and spreading the message that the dead will come back to life through Jesus.
So the temple guards arrested them. Since it was already evening, they put Peter and John in jail until the next day.
But many of those who had heard the message became believers, so the number of men who believed grew to about 5,000.
The next day the Jewish rulers, leaders, and scribes met in Jerusalem.
The chief priest Annas, Caiaphas, John, Alexander, and the rest of the chief priest's family were present.
