Acts 4:1-4

Now as they were speaking to the people, the priests, the commander of the temple police, and the Sadducees confronted them, because they were provoked that they were teaching the people and proclaiming the resurrection from the dead, using Jesus as the example. So they seized them and put them in custody until the next day, since it was already evening. But many of those who heard the message believed, and the number of the men came to about 5,000.
