While Peter was still speaking these words, the Holy Spirit descended upon all those who were listening to this message [i.e., Cornelius and his household].
“Who can keep these people [i.e., Cornelius’ household] from being immersed in water now that they have received the Holy Spirit just like we [apostles] have?” [See 2:4].
“And while I was speaking, [the power of] the Holy Spirit descended on them [i.e., Cornelius’ Gentile household] just like [it fell] on us [Jewish apostles] at the beginning [i.e., the day of Pentecost, See chapter 2].
Then Paul placed his hands on them and [the supernatural power of] the Holy Spirit came on them and they [began to] speak in [other] languages and prophesy [i.e., speak God's message].
And after they had prayed, the place where they were gathered shook, and these disciples were all filled with [the power of] the Holy Spirit and they were able to speak the message of God with boldness.
