While Peter was still speaking these words, the Holy Spirit came on all who heard the message. The circumcised believers who had come were astonished that the gift of the Holy Spirit had been poured out even on the Gentiles. For they heard them speaking in tongues and praising God.
Then Peter said, “Can anyone keep these people from being baptized with water? They have received the Holy Spirit just as we have.” So he ordered that they be baptized in the neame of Jesus Christ. Then they asked Peter to stay with them for a few days.
Acts 10:44-48
