1. While Peter and John were speaking to the people, some Jewish leaders came up to them. There were some priests, the captain of the soldiers that guarded the Temple, and some Sadducees.
2. They were upset because of what Peter and John were teaching the people. By telling people about Jesus, the apostles were teaching that people will rise from death.
3. The Jewish leaders arrested Peter and John and put them in jail. It was already night, so they kept them in jail until the next day.
4. But many of the people who heard the apostles believed what they said. There were now about 5000 men in the group of believers.
