[While] Peter was still speaking these words, the Holy Spirit fell on all those who were listening to the message.
References for Acts 10:44
And those believers from the circumcision who had accompanied Peter 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 glorifying God. Then Peter said,
"Surely no one can withhold the water for these [people] to be baptized, who have received the Holy Spirit as we also did!"
So he ordered [that] they be baptized in the name of Jesus Christ. Then they asked him to stay for several days.
