When the day of Pentecost had come, they were all together in one place. And suddenly a sound came from heaven like the rush of a mighty wind, and it filled all the house where they were sitting. And there appeared to them tongues as of fire, distributed and resting on each one of them. And they were all filled with the Holy Spirit and began to speak in other tongues, as the Spirit gave them utterance.
Now there were dwelling in Jerusalem Jews, devout men from every nation under heaven. And at this sound the multitude came together, and they were bewildered, because each one heard them speaking in his own language. And they were amazed and wondered, saying, “Are not all these who are speaking Galileans? And how is it that we hear, each of us in his own native language? Par′thians and Medes and E′lamites and residents of Mesopota′mia, Judea and Cappado′cia, Pontus and Asia, Phryg′ia and Pamphyl′ia, Egypt and the parts of Libya belonging to Cyre′ne, and visitors from Rome, both Jews and proselytes, Cretans and Arabians, we hear them telling in our own tongues the mighty works of God.” And all were amazed and perplexed, saying to one another, “What does this mean?” But others mocking said, “They are filled with new wine.”
But Peter, standing with the eleven, lifted up his voice and addressed them, “Men of Judea and all who dwell in Jerusalem, let this be known to you, and give ear to my words. For these men are not drunk, as you suppose, since it is only the third hour of the day; but this is what was spoken by the prophet Joel:
‘And in the last days it shall be, God declares,
that I will pour out my Spirit upon all flesh,
and your sons and your daughters shall prophesy,
and your young men shall see visions,
and your old men shall dream dreams;
yea, and on my menservants and my maidservants in those days
I will pour out my Spirit; and they shall prophesy.
And I will show wonders in the heaven above
and signs on the earth beneath,
blood, and fire, and vapor of smoke;
the sun shall be turned into darkness
and the moon into blood,
before the day of the Lord comes,
the great and manifest day.
And it shall be that whoever calls on the name of the Lord shall be saved.’
Acts 2:1-21 (RSV)
