Peter and John said that they needed to continue speaking about Jesus.

Acts 4:19-20

19 But Peter and John replied, “Would God think that it is right for us two to obey you and not to obey him? We(exc) will let you decide which of those you think is proper. 20 But as for us, we cannot obey you. We will not stop telling people about the things that we (exc) have seen Jesus do and what we have heard him teach.”
