Acts 2:14, 36-38

But Peter stood up with the eleven apostles, and in a loud voice he spoke to the crowd: “My fellow Jews, and all of you who are in Jerusalem, listen to me. Pay attention to what I have to say.

“So, all the people of Israel should know this truly: God has made Jesus —the man you nailed to the cross—both Lord and Christ.” When the people heard this, they felt guilty and asked Peter and the other apostles, “What shall we do?” Peter said to them, “Change your hearts and lives and be baptized, each 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.
