And the faithful ones that had come with Peter who were of those circumcised were amazed, because the free gift of the holy spirit was being poured out also upon people of the nations.

What God had opened up by means of the key-holder Peter remained open for an earth-wide witness. In agreement with this, God’s holy spirit “fell upon” (Greek: epipípto) three distinct classes of believers, (1) on the baptized 120 disciples and, afterward, about 3,000 converted Jews, all at Jerusalem on Pentecost of 33 C.E.; (2) on the baptized Samaritans, but only after the arrival and services of the apostles Peter and John; and (3) on the believing Gentiles gathered in the house of Cornelius in Caesarea, in 36 C.E.​—Acts 1:15; 2:1-4, 38, 41; 8:15-17; 10:44, 45; 11:15, 16.
