When they heard this, they came under deep conviction and said to Peter and the rest of the apostles: “Brothers, what must we do? ”
“Repent,” Peter said to them, “and be baptized, each of you, in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit. For the promise is for you and for your children, and for all who are far off, as many as the Lord our God will call.” And with many other words he testified and strongly urged them, saying, “Be saved from this corrupt generation! ”
So those who accepted his message were baptized, and that day about 3,000 people were added to them. And they devoted themselves to the apostles’ teaching, to the fellowship, to the breaking of bread, and to the prayers.
Then fear came over everyone, and many wonders and signs were being performed through the apostles.
