Our scripture reading for Pentecost Sunday is Acts 2:1-21 (Inclusive Bible): 

When the day of Pentecost arrived, they all met in one room.  Suddenly they heard what sounded like a violent, rushing wind from heaven; the noise filled the entire house in which they were sitting.  Something appeared to them that seemed like tongues of fire; these separated and came to rest on the head of each one.  They were all filled with the Holy Spirit and began to speak in other languages as she had enabled them. 

Now there were devout people living in Jerusalem from every nation under heaven, and at this sound they all assembled.  But they were bewildered to hear their native languages being spoken.  They were amazed and astonished:  “Surely all of these people speaking are Galileans!  How does it happen that each of us hears these words in our native tongue?  We are Parthians, Medes and Elamites, people from Mesopotamia, Judea and Cappadocia, Pontus and Asia, Phrygia and Pamphylia, Egypt and the parts of Libya around Cyrene, as well as visitors from Rome—all Jews, or converts to Judaism—Cretans and Arabs, too; we hear them preaching, each in our own language, about the marvels of God!”

All were amazed and disturbed.  They asked each other, “What does this mean?”  But others said mockingly, “They’ve drunk too much new wine.”

Then Peter stood up with the Eleven and addressed the crowd:  “Women and men of Judea, and all you who live in Jerusalem!  Listen to what I have to say!  These people are not drunk as you think—it’s only nine o’clock in the morning!  No, it’s what Joel the prophet spoke of:  
‘In the days to come—
it is our God who speaks—
I will pour out my Spirit
on all humankind.  
Your daughters and sons will prophesy, 
your young people will see visions, 
and your elders will dream dreams.  
Even on the most insignificant of my people, 
both women and men, 
I will pour out my Spirit in those days, 
and they will prophesy.  
And I will display wonders
in the heavens above
and signs on the earth below:
blood, fire, and billowing smoke.  
The sun will be turned into darkness
and the moon will become blood
before the coming of the
great and sublime day of our God.  
And all who call upon the name
of our God will be saved.’”
