1. While Peter and John were speaking to the people, a group of men came up to them. There were Jewish priests, the captain of the soldiers that guarded the Temple, and some Sadducees.
2. They were upset because the two apostles were teaching the people. Peter and John were preaching that people will rise from death through the power of Jesus.
3. The Jewish leaders grabbed 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 those who heard Peter and John preach believed the things they said. There were now about 5,000 men in the group of believers.
21-22. The Jewish leaders could not find a way to punish them because all the people were praising God for what had been done. (This miracle was a proof from God. The man who was healed was more than 40 years old!) So the Jewish leaders warned the apostles again and let them go free.
