Acts of the Apostles 2:37-43

When the crowd heard this, they were deeply troubled. They said to Peter and the other apostles, “Brothers, what should we do?” Peter replied, “Change your hearts and lives. Each of you must be baptized in the name of Jesus Christ for the forgiveness of your sins. Then you will receive the gift of the Holy Spirit. This promise is for you, your children, and for all who are far away—as many as the Lord our God invites.” With many other words he testified to them and encouraged them, saying, “Be saved from this perverse generation.” Those who accepted Peter’s message were baptized. God brought about three thousand people into the community on that day. The believers devoted themselves to the apostles’ teaching, to the community, to their shared meals, and to their prayers. A sense of awe came over everyone. God performed many wonders and signs through the apostles.
