Acts 2:37-41 New American Standard Bible (NASB)
37 Now when they heard this, they were [a]pierced to the heart, and said to Peter and the rest of the apostles, “[b]Brethren, [c]what shall we do?” 38 Peter said to them, “Repent, and each of you be baptized in the name of Jesus Christ for the forgiveness of your sins; and you will receive the gift of the Holy Spirit. 39 For the promise is for you and your children and for all who are far off, as many as the Lord our God will call to Himself.” 40 And with many other words he solemnly testified and kept on exhorting them, saying, “[d]Be saved from this perverse generation!” 41 So then, those who had received his word were baptized; and that day there were added about three thousand [e]souls.
Acts 2:37-41 New International Version (NIV)
37 When the people heard this, they were cut to the heart and said to Peter and the other apostles, “Brothers, what shall we do?”
38 Peter replied, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit. 39 The promise is for you and your children and for all who are far off—for all whom the Lord our God will call.”
40 With many other words he warned them; and he pleaded with them, “Save yourselves from this corrupt generation.” 41 Those who accepted his message were baptized, and about three thousand were added to their number that day.
