The Jewish leaders commanded the two apostles to stop teaching people about Jesus.

Acts 4:15-18

15 So the Jewish leaders commanded guards to take Peter, John, and the man outside of the room where those leaders were meeting. After they did so, the leaders talked with each other about Peter and John. 16 Being frustrated, one after another, they said, “◄There is really nothing that we can do to punish these two men!/How can we (inc) do anything to punish these two men?► [RHQ] Almost everyone [HYP] who is living in Jerusalem knows that they have done an amazing miracle, so we cannot tell people that it did not happen! 17 However, we must not allow other people to hear about this miracle. So we must tell these men that we will punish them if they continue to tell other people about this [MTY] man who they say gave them the power to do it.” 18 So the Jewish leaders commanded guards to bring the two apostles into that room again. After they did so, they commanded them both that they should never speak about Jesus, and they should not teach anyone about him [MTY] again.
