Acts 10:44-48
10:44 While Peter was still speaking, the Holy Spirit fell upon all who heard the word.

10:45 The circumcised believers who had come with Peter were astounded that the gift of the Holy Spirit had been poured out even on the Gentiles,

10:46 for they heard them speaking in tongues and extolling God. Then Peter said,

10:47 "Can anyone withhold the water for baptizing these people who have received the Holy Spirit just as we have?"

10:48 So he ordered them to be baptized in the name of Jesus Christ. Then they invited him to stay for several days.
