Acts 2:14a, 36-41
2:14a: But Peter, standing with the eleven, raised his voice and addressed them,
2:36 "Therefore let the entire house of Israel know with certainty that God has made him both Lord and Messiah, this Jesus whom you crucified."
2:37 Now when they heard this, they were cut to the heart and said to Peter and to the other apostles, "Brothers, what should we do?"
2:38 Peter said to them, "Repent, and be baptized every one of you in the name of Jesus Christ so that your sins may be forgiven; and you will receive the gift of the Holy Spirit.
2:39 For the promise is for you, for your children, and for all who are far away, everyone whom the Lord our God calls to him."
2:40 And he testified with many other arguments and exhorted them, saying, "Save yourselves from this corrupt generation."
2:41 So those who welcomed his message were baptized, and that day about three thousand persons were added.
